--- Comment #15 from Tobias Jakobi liquid.acid@gmx.net 2008-06-19 10:08:09 --- Hi Austin,
see this bug: http://bugs.winehq.org/show_bug.cgi?id=10229
Both are somehow connected. Means the connecting problem also appears when not hosting a dedicated server. Also it's dependent on "intercommunication" between windows and wine. For example when hosting a non-dedicated server in wine, another SS client running on wine (and on a remote system) can join the game. A windows client is unable to do so.
So this is not fixed...
Greets, Tobias
