Painting problems.

I'm having a problem with resizing a window and control not being painted properly....

I have 3 controls in the bottom right hand corner which are moved when the window is resized. If you take a look at the attached file you will see the result. This happens sometimes... like if I click and resize the window quickly, but if I do it more slowly it doesn't

Anyone having any ideas on how I can fix this?

A call to MoveWindow that changes only the position does not need to repaint the window, so pass FALSE as the bRepaint and invalidate the uncovered area yourself (I know this is tedious, but I think it will improve the performance and maybe solve your problem.
