This is definitely an odd one...We have had three editors on two different MacPros in two different projects experience runaway playhead situations.
Basically, the editor will be playing back a sequence, and lose control of playback. Neither the keyboard nor mouse work in Avid (but they can navigate Finder and force-quit Avid fine). So esentially the playhead will continue on until it reaches the end of the timeline, at which point the only way to gain control of Avid again is to force-quit it. Unfortunately, this means I don't have any crash logs dig through.
Wondering if anyone else has seen this come through.
We've tried full uninstall / reinstall. Removed the AJA. Switched to an Avid DNxIO. Removed the "OpenIO Virtualization Plugin." Even did the fun old "displays have spearate spaces" toggle that Avid Support loves.
