--- Comment #30 from Roderick Colenbrander thunderbird2k@gmx.net 2008-08-14 15:37:17 --- The bug is limited to Nvidia only because they are the only ones at the moment who offer support for pbuffers. Ati dropped it a while ago or they aren't advertising the extension properly.
Attach a +wgl log from a recent Wine version.
