--- Comment #5 from Roderick Colenbrander thunderbird2k@gmx.net 2008-05-14 01:38:15 --- For some reason the wgl log is not complete. Perhaps the application uses multiple GL threads. Try to explicitly set WINEDEBUG=+wgl in your shell and then run wine again and pipe all wgl output to a log file.
Upto now it looks like no pixel format was set on hdc 0xbd04 which leads to the problem.
