--- Comment #177 from Martin Bosner cleric@x-ion.de 2008-03-30 15:36:20 --- Sorry about my last comment but i was a little bit pissed about the "here everything is fine... are you sure that it is not you" stuff.
Its a wine implementation bug of accept_ex and not my mistake.
Yes it does not occur in normal BNET HOSTED (bnet is distributing game data at normal slow mode).
The "Grey screen bug" does also occur on windows but not nearly as many times (feeled) as in windows. That may happen because of packets the host is sending to the client that tells him "game is full" or something. I tried pretty hard but never got a "game is full" message with the patch. Maybe there is a starting point for bug hunting.
