If you experience errors while taking a test through the LockDown Browser, check your security settings in IE and the overall functionality of IE. IE should be reset to default security levels, and the exam should be tried again.
The following tips may help to correct other problems encountered with Lockdown Browser.
Only use Respondus LockDown Browser for testing purposes.
If you attempt to use the browser to access additional course content, like lecture notes or worksheets, it may cause the program to encounter a problem and freeze or close. This usually occurs when the content you are attempting to access is a Word, PowerPoint or Adobe Acrobat related file. The browser cannot open the external program needed to run these files because of the browser’s restricted nature and it creates an internal error with the software. If you need to view these files, please use a regular browser like Mozilla Firefox.
If you are having problems installing LockDown Browser on a Windows system, we recommend the following additional steps:
Because the LockDown Browser is a shell that sits on top of an Internet browser (Internet Explorer for PC users and Safari for Mac Users), we recommend students access their course with either Internet Explorer or Safari and take a non-LDB enabled practice quiz to resolve any settings and media plug-ins prior to taking a test with LockDown Browser.
For Windows systems, we suggest relaxing any security settings to “medium”, add “LockDown.exe” as a trusted application and “*.uwyo.edu” address as a trusted site in any security software.
We strongly recommend using an Ethernet (wired) Internet connection with a speed of at least 512 Kbps or higher while taking your exam in LockDown Browser. If you use a wireless, USB modem, laptop connect card, or mobile hotspot connection during an exam, you are more likely to run into problems due to dropped/interrupted connections to the Canvas server. This is because the Canvas server is more bandwidth intensive (especially during exams) than normal Internet surfing.
If you lose your Internet connection during the exam, it will lock up the browser and not allow you to save answers, move on to other questions, submit or exit the exam. Ethernet connections are the most stable connection to the Canvas servers. If you have a router, plugging directly into it when taking exams will reduce the chances of connection interruptions.
If you are getting an error when you attempt to open the LockDown Browser that says “You may not have the appropriate permissions to access the item”, it may be an issue with the permissions on your system or antivirus software.
Respondus LockDown Browser uses the same HTML engine, system components and settings as Internet Explorer (Windows) and Safari (Macintosh). Basically, LockDown Browser provides a custom interface for the Internet Explorer (Windows) or Safari (Mac) browsers that are already installed.
We recommend completely uninstalling the software and doing a new installation while directly logged into the system as a local administrator with full rights (see instructions above for full details).
This occurs when there is a second level link being accessed from a primary level link. However, link blocking usually does not occur until the student enters a quiz and starts accessing links within a quiz. Usually, this comes from configuration issues with the underlying Internet Explorer browser components.To resolve this issue, please try the following:
The LockDown Browser is programmed to detect when conflicting programs are still running and will request that you close these programs. Some programs like the Dell Dock and Google Toolbar run as a background process on your computer and will have to be shutdown before you can proceed in the LockDown Browser. You can usually turn these programs off through the task tray or, in the case of the Dell Dock, by right clicking on the application and clicking Exit.
In some rare instances, these programs running in the background can cause the LockDown Browser to lock up or stop responding. Programs that use Java or the Internet such iTunes and other media managers, file sharing agents like Bittorent, and instant messenger applications have a higher risk of causing the LockDown Browser to lock up. It is best to close every program on your computer before starting the LockDown Browser.
If the LockDown Browser stops responding before you start an exam or if you see a blank page that fills the computer screen, this could be due to security windows that have popped up behind the LockDown browser. If you have not started the exam, close the browser and address the security pop-up windows. You should be able to reopen the browser without issue. However, if you have started the exam, the only known workaround is to restart your computer and address the pop-up windows before beginning the exam.
If you lose your Internet connection while taking an exam or if you have outdated and/or multiple Java installations, the LockDown Browser and your computer may stop responding or freeze. Currently, the only way to resolve this issue is to do a hard shutdown (i.e. unplugging all power from the computer including power cables and/or batteries if you are using a laptop). If you are missing your Start Menu, Task Bar or are unable to access the Task Manager after doing a hard reboot, you can restore these applications by restarting the LockDown Browser and exiting the software properly.
Depending on your system, this could take several minutes and will cause you to lose time on the exam. In most cases, as long as the time has not expired, it should let you back into the exam. As soon as you have completed the exam, immediately e-mail your instructor to let them know what happened.
Occasionally, Respondus will release a new version of the LockDown Browser. When a new version of LockDown Browser becomes available, the system will prompt you to update your installation of the software.
Whenever you update your LockDown Browser, you may also want to do the following:
