Blank Page When Opening LockDown Browser

When opening LockDown Browser, the browser will display the Blackboard page (toro.csudh.edu). If the page does not load and displays a blank page, the computer is blocking access to Respondus servers.

Temporarily disable or shut down anti-virus and firewall software on your computer and reopen LockDown Browser. LockDown Browser will load Blackboard. Sign in and take the test.

After taking and finishing the test, enable anti-virus and firewall software.
