Trillian crashes, can''t rejoin group chat unless Wildfire restarted

I have Wildfire 3.1.1 setup on a Windows XP Pro machine – I run from a Trillian client, others in my office use other clients – Trillian Pro is a little fragile at times with Jabber, and likes to crash on occasion. When it does, I can’'t seem to reconnect to the group chat room I was in when I crashed no matter what I do, unless I restart the Wildfire server (which of course kicks everyone else not having problems out).
