Ack! I have a perplexing question...

I am writing an application with the SDK. The problem I am having is that
whenever I process a WM_PAINT message, it seems that the entire window has 
been invalidated and that it must repaint the whole thing. This is not
supposed to happen. 
At one point I invalidate a small section of the window, but very carefully.
I know that if I try to InvalidateRect with my lpRect == NULL, it will
invalidate the whole thing, but I am careful, and am only invalidating
a small section. Somebody at Microsoft tech support suggested that it might
have something to do with the way I created my window. Anybody happen apon
a similar weirdity? Any suggestions?

Thanks,

 Anthony Green
