UT2003 Windowing Regression - Another nights effort...

[Ann and Jason Edmeades]

I think I have reproduced the same problem with a simple testpgm...

Instructions...

1. Start Visual Studio, create a default windows application
2. Comment out the code in the WM_PAINT and replace it with return 1
(important)
3. Run it...

On windows you can play with the menu etc and it works. The CPU is at 100%
but clicking on menu items works, and menu->exit does actually exit the app.
(Menu->About causes a hang)

On wine you get the infinite loop and the screen/menu never gets as far as
being drawn

Note:Its important to to return the 1 (or TRUE) - returning 0 works fine on
both!

Question... Is wine being too proactive - Perhaps in the case where the
redraw is unsuccessful then wine should schedule a WM_PAINT rather than
performing it?

Note: UT2003 seems to just do:
CreateWindowEx(AppWindow, Visible+..., )
ShowWindow(show no activate)
UpdateWindow(rdw all children, updatenow)
**hang**
