I was having the same problem. I completely erased the Prefs and now it works just fine. Have you tried this muzzynyc?

Still haven't found how to fix it, tried logging out, rebooting, re-installing Adium, but so far nothing worked, guess I'll have to stick with 0.89.1 for now...
Edit: Forgot to say trying version 1.0 (not Beta) on a 12" iBook running OS X 10.4.8

djmori, I guess that's not it, when I try to open a conversation window, all my contacts (even online ones) disappear, altough the status says I'm online. Is this what you are experiencing mafr?
