Regression in 'Zoo Tycoon 1 demo'

[Paul Vriens]

Hi,

as of patch http://cvs.winehq.org/patch.py?id=15812 there is a
regression in this demo. The first window stays black and logging shows
that the app is looping (so it seems) on WM_PAINT messages:

Call window proc 0x453bb0
(hwnd=0x20022,msg=WM_PAINT,wp=00000000,lp=00000000)

loads of these at the end of the trace.

Does the looping have anything to do with
http://www.winehq.org/hypermail/wine-cvs/2004/10/0395.html ?

What could be the next step to isolate the problem?

Cheers,

Paul.
