Learn@UW/D2L - Problem Accessing Live Rooms in Online Rooms Using Safari
If you are using Safari, you may encounter difficulties accessing live rooms in the "Online Rooms" tool.
The symptom is that Blackboard Collaborate doesn't launch when you click on the live link for a room.
The problem occurs if you have Safari's popup blocker turned on. If you turn off the popup blocker (click on Safari in the toolbar, and select "Block Pop-Up Windows" to uncheck it), you will be able to launch Blackboard Collaborate.
