--- Comment #23 from Pigeon pigeon@pigeond.net 2010-07-17 08:21:47 --- I have had this problem before where Garena is not able to start War3 properly at all, not even to the main screen. And since (I assume) War3 does not try to do any network stuff until you click on the LAN game button, I suspect this is not the same as the 16047.
Though I could not reproduce this problem anymore, either because of a newer wine, or a newer Garena.
