Apple DVD Player-like screenshot censor / keystroke event handler priority?

Question

I am really interested on a way to restrict a fragment of my application to screenshots.
I've managed to handle screenshot keystrokes and almost achieved what i wanted, BUT!
Currently i'm struggling to fix problem with race condition between os' screenshot process. Usually i am first and i am able to hide part of my app against screen grabber, but that't not the rule. Sometimes my event handler is slower, than screen grabber.
My question is - is it possible to increase event handler priority / main thread priority, so my app will receive all keystrokes with increased priority?
Thanks in advance!

The Fade In-Out behavior in the library palette
animation\animation
might give you some ideas.
It is time basedd (fewer courser steps on slow systems) and
works in
background.
It looks like you might be able to extend the mFadeActivate
handler to
work with your menu stuff
Here's a rough example
on mFadeActivate me, finalBlend, totalMS, excludeSprite
To bring in menu sprite 10 and turn down any others mid
process:
sendSprite(10, #mFadeActivate, 100, 500, 0)
sendAllSprites(#mFadeActivate, 50, 0, 10)
The second call sets all other elements to 50% blend in 0
time, except
sprite 10
if excludeSprite = me.spriteNUm then exit -- this line
handles the
exclued sprite num
