Ok, I know this sounds crazy and I would not post it except for the fact that it has repeatedly happened with the same occurence since I loaded CS3. When I click on the Video Effects panel and slide it to the left (making the bin panel smaller and the effects panel larger) I sometimes get a "serious error" and the program shuts down almost immediately. It does not occur every time, but has happened at least 15 times at this exact point. It's strange that a manual change in the GUI would cause this. Has anyone else experienced this?
