- Hi. Whenever a window covers up some or all of you application's window and
- is then removed (presumably to re-expose your window), Windows "invalidates"
- the overwritten portion of your window and sends your application a WM_PAINT
- (that should be WM<underscore>PAINT -- for some reason my underscore isn't
- working) message telling you what part of the window has been destroyed and
- that you need to "repaint" it. Sounds like you're either not responding to
- this message, or for some reason it's just not getting to your message handler.
