I too have found gaim to be slightly buggy. When someone tries to send me a file over Direct IM, it stops doing stuff. I have to kill it and relaunch it. Then, if someone sends me a hyperlink and I hover my mouse over it, it quits. Just diappears. So I've gotta be real careful like. Other than that it works great (version .59 didn't have these problems that .72 does though).
