--- Comment #4 from Roderick Colenbrander thunderbird2k@gmx.net 2008-04-20 02:55:50 --- The correct Xserver version is VERY important. In various versions the opengl implementation is broken. In some cases it enters an infinite loop and crashes due to that in other versions you can get such issues. I'm not sure if it should work fine at all as even when it finds opengl you need several hacks in Wine to get opengl in a usable state.
