SCORM 1.2 and AICC hangs firefox when exiting. Also, no audio is heard. IE 7 is smooth.

Error says: callmethod: media_003_video TickTimer undefined. From what I can tell from the hang, it appears to be due to the interaction between the presentation and the browser, but nothing inside of Moodle.

Please let me know if there is a fix. I need the training up for a client.
