App works almost perfectly, but one MDI screen won't draw

Yeah, that's the big that usually gets me :) Are they the sort of
messages that should be generated by Wine or the app?

What happens if the app doesn't call BeginPaint in a WM_PAINT handler.
Is that an API violation, or are there reasons for it? MSDN had an
explanation that seemed to suggest that in certain unusual circumstances
you didn't need to call it, but I don't remember exactly what.

How common is it for apps to actually make bad API calls? QuickTime
seemed to do that, is it rare or not?
