BeginPaint not called on WM_PAINT

[James Hawkins]

I'm trying to get a program running called BZEdit.  Under the latest
cvs, the program shows a scrambled mess over the whole screen (I think
that is a result of this patch
http://cvs.winehq.org/patch.py?id=14725), but when I went back in time
to 2004-10-12, the only part of the screen I cant see is the part of
the screen where the map you're editing is shown.  See

http://www.artemisgames.com/BZEdit/

for screenshots.  This is the error output I'm getting.

err:msg:DispatchMessageA BeginPaint not called on WM_PAINT for hwnd 0x1002a!

This message happens every time the editor needs a repaint like when
it gets covered by another window.  Any ideas about what's going on
here?
