Designate the 缅北强奸 Blackboard site as a "Trusted" site (Internet Explorer only).
Internet Explorer will allow you to place sites in a "Trusted" zone where the security settings are much less restrictive then they normally are. Placing the 缅北强奸 Blackboard site on this list has fixed a number of access issues that occur due to restrictive security settings.

This page is to provide tips to faculty to help them prepare students for using Respondus Lockdown Browser and to help students troubleshoot problems they may encounter when using the lockdown browser.

Lockdown Browser errors are usually specific to a particular system setup, so there is no definitive list of what may cause a problem and what will not. As we encounter problems with Respondus Lockdown Browser, we will provide fixes and workarounds where possible, and error reports where workarounds cannot be found.

Tips for Instructors聽

Create a mock exam for Lockdown Browser

Instructors are聽highly聽encouraged to provide a mock test using Lockdown Browser before聽every聽quiz/exam they plan on giving students using the Lockdown Browser.

Problems students encounter using Lockdown Browser can, in many cases, be resolved by first taking a mock exam using the Lockdown Browser, working out any bugs using the mock exam, then taking the real exam. If you use any features in your test that require a plugin to work, namely Flash, you must include a question that requires the plugin in your mock exam. This will ensure that the student's machine is configured correctly to run the plugin in Lockdown Browser.

Unfortunately, many of the problems users are encountering can be fixed once, then appear again after a restart of their computer, hence the need to provide a mock exam before each quiz/exam.
Modifying the "Password" field in the Test Options in Bb when using the LockDown Browser

If you use Respondus LockDown browser to deploy a locked-down test, do not make any modifications to the "Password" field in the Test Options area in Bb, even if you do not want a password on the quiz/exam. Unchecking the box or erasing/modifying the password will cause multiple problems when students try to take the test using the LockDown Browser, and you can potentially disable the LDB requirement on the exam, which would allow the student to take the exam in a non-locked-down environment.

Troubleshooting for Students聽

Launching the correct browser to take a quiz/exam in Lockdown Browser

After you install Lockdown Browser, you must use the Lockdown Browser link on your Desktop to take a quiz/exam in Blackboard. If you launch Internet Explorer or Firefox as you would to normally access Blackboard, you will not be able to take the quiz/exam. If the icon you use does not say "Lockdown Browser", then you are using the wrong icon.
Using a mock exam to eliminate bugs in Lockdown Browser

If your instructor provides a mock exam using Lockdown Browser, we suggest you take the mock exam聽immediately聽before you take your actual exam using Lockdown Browser. After you have taken the mock exam, do no restart or make changes to your computer, as they may cause bugs to reappear during the actual exam.
Lockdown Browser stops responding after you enter your Blackboard course, but before you start the test.

Issue:聽Some windows that pop up due to security restrictions may appear聽产别丑颈苍诲听the Lockdown Browser window for Blackboard. These pop-ups require the user to click through them before taking you to the next Blackboard page. When this occurs, the Lockdown Browser will just sit at a blank page waiting for you to click the security pop-up before proceeding. Because Lockdown Browser will not let you move or resize a window, you cannot get to the pop-up, resulting in an effective freeze of the browser.

Workaround:聽Since you are not yet in the exam for the course, you can still close the Lockdown Browser. Closing the Lockdown Browser will allow the security pop-up to be seen, at which point you can click "OK". Relaunching the Lockdown Browser after clicking through the security pop-up will allow you to proceed to the exam without problem. This works聽only聽if you relaunch the Lockdown Browser immediately after you close the pop-up window. If you go to another website, restart your computer, or make any changes to your computer, you may encounter the problem again after restarting the Lockdown Browser.
After launching an exam in Lockdown Browser, you just see a blank page that fills the entire screen.

Issue:聽A pop-up requires attention, and is hidden behind a full screen Lockdown Browser window. Because you have already started the exam, Lockdown Browser will not allow you to close the program, resize, or move the window. Therefore, you cannot get to the pop-up window, and your computer is effectively locked.

Workaround:聽There is no known workaround for this problem at the moment. We are working with Respondus to provide a workable solution. If this happens, you'll need to restart your computer by powering off the computer, then powering it back on.
You lose your internet connection while taking an exam with Lockdown Browser

Issue:聽If you lose your connection to the internet while taking a test using the Lockdown Browser, it will freeze the Lockdown Browser program.

Workaround:聽There is no known workaround for this problem at the moment. If this happens, you'll need to restart your computer by powering off the computer, then powering it back on. Your instructor will have to reset your test in Blackboard before you will be able to take it again.
The Lockdown Browser request you to close other programs

Issue:聽Other programs running in the background can cause the Lockdown Browser to lock up.聽 Programs that use java or the internet have a higher risk.

Workaround:聽Close every program on your computer before starting the Lockdown Browser.聽 Instant messaging, media managers like iTunes, file sharing, chat, internet and other java based programs should definitely be closed.
The Lockdown Browser closes or locks up in the middle of a test

滨蝉蝉耻别:听If you have already done all the steps above there could be a problem with your Java.聽 If it is a problem with your Java, you are likely having problems with Internet Explorer 8 as well.

奥辞谤办补谤辞耻苍诲:听Go to聽聽and download the latest version of java.

If you are having problems with Blackboard that are not listed here otherwise, you'll want to check that you are using an internet browser that is compatible with Blackboard, and that the browser is correctly configured to allow Blackboard to work properly.

A list of internet browsers that are compatible with Blackboard can be found聽. If you are not using a browser that is Blackboard compatible, we suggest switching to one that is.

If you are using a browser that is compatible with Blackboard, but are still having problems within Blackboard, you'll want to check that your browser is configured in a way that allows Blackboard to work properly. Take the following steps to ensure that your browser is configured correctly.

Designate the 缅北强奸 Blackboard site as a "Trusted" site (Internet Explorer only).
Internet Explorer will allow you to place sites in a "Trusted" zone where the security settings are much less restrictive then they normally are. Placing the 缅北强奸 Blackboard site on this list has fixed a number of access issues that occur due to restrictive security settings.

To set 缅北强奸 Blackboard as a "Trusted" site, go into the "Internet Options" area of IE (Tools > Internet Options) and click the "Security" tab. Then click the "Trusted sites" icon and then the "Sites" button. If the box next to "Require server verification (https:)..." is checked, uncheck it then type "bb.usi.edu" into the "Add web site to this zone:" area and click the "Add" button. "blackboard.usi.edu" should then appear in the "Web Sites:" area. Click "Ok". Blackboard is now a "Trusted" site.

You should be back at the "Security" tab screen and "Trusted Sites" should still be highlighted. You will now want to verify that Blackboard is running the least restrictive security settings. Click the "Default Level" button. The security level should read "Low". If it does not, drag the slider down to "Low" and then click "OK". Close all browser windows and restart the browser and try accessing again.

Clear your cache.

When trying to access certain areas in Blackboard, you may be pulling a cached page that prevents you from properly logging in to the system. Clearing your cache will prevent this. Perform the following based on the browser you are using.

Internet Explorer	Tools Menu > Internet Options > General tab > Browsing History > Click "Delete". Check "Temporary Internet Files". Uncheck everything else. Click "Delete". Restart the browser before trying again.
Firefox	Tools Menu > Clear Private Data > Check "Cache". Uncheck everything else. Click "Clear Private Data Now". Restart the browser before trying again.

Enable JavaScript

Much of Blackboard's functionality depends on JavaScript. With JavaScript turned off, many tasks are impossible, such as taking quizzes and using the wisiwyg editor.

Internet Explorer	Tools Menu > Internet Options > Security tab > Custom Level > Scripting (near bottom): Choose "Active Scripting: Enabled" and 鈥淪cripting of Java Applets: Enabled鈥�.
Firefox	Tools Menu > Options > Content. Check "Enable Java" and "Enable JavaScript" . Click the "Advanced" button and check "Change Status Bar Text" and UNcheck "Hide the status bar".

Firefox	Tools Menu > Options > Content Tab > Block Popup Windows : Exceptions > Allow popups for blackboard.usi.edu and blackboard.usi.edu:8011.
Third Party Pop-up Blockers	If using a third-party popup blocker, make sure it allows popups for blackboard.usi.edu and blackboard.usi.edu:8011. If you can't configure your popup blocker to allow popups from certain sites, you will have to either turn it off or get one that allows specific popups.

Disable Mixed Mode Security Warnings (Internet Explorer Only)

Security warnings that appear in IE may cause confusion when trying to view content in Blackboard. Make the following change to disable these warnings.

Internet Explorer

Tools Menu > Internet Options > Security Tab > Custom > Set Mixed Mode option to Enable.

Firefox

Not Applicable

Make sure there are no programs running on your computer that interfere with Blackboard.

In some cases, third party programs, such as download managers, security suites, firewalls, etc... will cause problems with certain Blackboard functions. For instance, having a download manager running may prevent you from being able to upload or download files from Blackboard. If you are running into a problem on Blackboard that is not discussed above, and your browser is compatible with Blackboard and configured correctly, we suggest turning off any other programs you are running (including background processes), to see if that fixes the problem.
