Good catch, thanks Leon.  This had to do with the process of  
capturing and releasing the screen.

Considering this and John's feedback, I'm altering the way Video Cues  
go full screen.  The display will no longer be exclusively captured  
by QLab, so things like the force-quit dialog box and Expose will  
continue to work on the screen showing the video.  This also fixes  
the problem described above.

One change this does make is that going full screen will not  
automatically provide you with a black background, for example when  
fading a full screen video in from zero visibility.  Simply drop in a  
solid black image if you want a black background.

Thanks,
