I have got a stack here ("Multiple Choice Tutorial"; see my website) 
that uses integrated "transparent" answer and ask dialogs, where the 
transparency is produced by taking a snapshot of the rect beneath the 
dialog, which is then masked by a translucent overlay image to achieve 
the effect of semi-transparency of the dialogs.
No flashing occurs on WindowsXP with the latest Rev engine of Nov 19th, 
and none with earlier versions

I compared the scriptlines responsible for taking the snapshots in 
"GetInLine" and "Multiple Choice Tutorial" and found no relevant 

The one difference of the "Multiple Choice" stack is that I set the 
backdrop. If I remove the backdrop, then I get a flashing, but only at 
the bottom line of the screen.
The same holds (of course) for your stack. With the backdrop set to any 
color there is no visible flashing.

Such a workaround is probably not always feasable - depending on the 
intentions for the design of a stack - and it would be nice to find a 
general solution of this snapshot-flashing problem.
