If you are using Internet Explorer (IE) to access Blackboard, IE will attempt to block VoiceThreads from showing up.

To make VoiceThreads appear in BlackBoard:

Refresh your browser. A dialogue box should appear (see below).If this box appears, click "No."

Example of the dialogue box from Internet Explorer 8 and earlier

Example of the dialogue box from Internet Explorer 9 - this box will appear at the bottom of the screen.

If that does not fix the problem, try accessing Blackboard with another web browser, like Mozilla Firefox or Google Chrome.
