I'd like to do something similar, though not for the same reason I suspect.

What I want is a transparent window the full size of the screen which
is always on the top of the window `stack' and which can intercept all
events from the user and filter out some for its own use and pass the
rest on.  It will _not_ respond to the user directly who won't know
its there and it will not prevent what's underneath it being updated
(exposure events etc.)

(BTW it's for a purely innocent purpose before anyone suspects
otherwise) 

Is there a way to do this (or something which would provide the same
intercept facilities) at the application level ?  (if not its back
into the server code ..splash.. . glug . glug . glug )

Thanks

  Roddy
