flashing using deep mask

Mon Apr 17 15:36:05 EDT 2006

I have a stack whose windowShape is set to the ID of a png with a 
transparent background (i.e., alpha mask).  This lets me change the mask 
without the stack window flashing; however, I now get flashing when I 
display a .png over the backgound png, and it seems I can no longer 
interact with my Quicktime movies.   It also won't let me use a unlock 
screen with visual effect dissolve to display the stack.

What am I doing wrong?
