------- Additional Comments From tom@dbservice.com 2007-24-06 15:03 ------- Hm.. interesting, because it doesn't crash in wine if wine provides more than one pixelformat to the WoW. And I still think it's an off-by-one bug in WoW: according to the +wgl trace WoW first queries num-pixel-formats and then iterates over all PFs to check their attributes, but it will never check the very last one, so if num-pixel-formats is one, it won't check any PF and crash later (probably because of uninitialized memory or such). The question is, why does it also crash on WinXP? I doubt that WinXP provides only one PF to WoW.
Anyway, did you report it to Blizzard? (.. and did you get any feedback?)
