Windows doesn't use SetWindowPos to update the disabled Close button, but draws the button directly.
Actually that doesn't look right either, we shouldn't bypass the normal painting code IMO; but RedrawWindow(RDW_FRAME) would probably work better than SetWindowPos.
Probably RedrawWindow(RDW_FRAME) would be better, but under Windows a window doesn't receive WM_NCPAINT in that case either.
