can you elaborate on this.. I tried basic modal on top of modal when I was 
testing out the close/hide fix, and things seemed to work okay, but so far 
you and I see seem to be on different worlds when it comes to these 
problems. ;-)

nice imagery... I like.. :)

hmmm. I would suggest first going back to the way it was, because I am 
having absolutly no issues with your control, on modal forms, on modal on 
top of modal et-al, so long as it uses show, not showmodal on the popup 
form.  If you continue to have issues.. post them. better to try and do 
things the proper way, and fix any issues resulting, then create a hack and 
still have to go back and fix things later, after all these things are 
problems in the LCL, which should be fixed anyway, and if I or anyone else 
can fix them all the better for everybody, not just you.

It is possible on a purely GTK level. but there is that again.

I think it would be a good idea to be able to intercept these sorts of 
things on a LCL level, so that any control can create its own interceptions 
for special purpose controls etc. however this is rather complex and while I 
understand the basics, because I do not have the experiance it would take me 
days perhaps weeks to figure out this by myself, so ... perhaps later.
