------- Additional Comments From thunderbird2k@gmx.net 2007-27-07 04:25 ------- I guess the issue is that the program doesn't like the pixelformat we are returning. I'll see what can be done about it. Further is the program also using glut32.dll? As that can cause additional issues too (for this reason glut32.dll was dropped from wine and that's why a native glut32 is needed these days).
