Well, I don't know where the problem lies but I do know this. I can connect Mirc & Xchat to the same server at the same time, under both Linux with Mirc running under Wine or both under Windows and Mirc will timeout continously where Xchat stays connected for days on in without a single timeout. This is on a private server running Ultimate 3.0.0.a30 with only a few users ever connected to it. Some of the other users have verified the same thing with this particular server and others.
