  Thank you Derek and Greg,
 
What I am really tring to do is place a button in a window with a constantly
moving pixmap. (not a game). I will try Dereks idea of putting a smaller pixmap
in the window and Greg's idea of putting the button below the pixmap.

I haven't tried anything yet as I just got home from work and just read your
posts. I'm tired now and will do it later but I don't see any reason it won't
work.

Thanks again,


Don Cole
