How do you test this under Windows ?
In my test app, I have a white brush as class brush. So my window is white.

If I add after the BeginPaint :

GetClientRect(hwnd, &r);
r.top += 200;
FillRect(ps.hdc, &r, (HBRUSH) COLOR_WINDOW)

the lower part of my window is painted with the beautiful window color (brown)

Now if I add immediately after  :

hdc = GetWindowDC(hwnd);
SendMessage(hwnd, WM_ERASEBKGND, (WPARAM) hdc, 0);
ReleaseDC(hwnd, hdc);

I get a window that is completely white; maybe I am missing something but
I should see a small brown strip at the lower part of the window, corresponding
to the caption + menu height, no ?
