Good points, thanks for the reminder Havoc.

Maybe we really do need to makes these changes - because as I said, with 
the advent of alpha visuals on X, things are about to get even more 
complicated, and I don't see a better way allow popups to coexist 
successfully with "really really on top" AT windows that intersect them 
in the 2d projection of the display (i.e. popups that need to pop 
"under" an AT window).

I'll be off the air, myself for a couple of weeks, and maybe we are 
straying away from the original topic a bit.  Nonetheless I think we've 
raised a key question - maybe someone will come up with a brilliant 
solution while I am away :-)
