What if the LockDownBrowser stops responding before I start the exam?

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.
