Yeah... I went back to AIM today after trying to get Fire 0.22 working. It would kick me off after a minute or two. I heard that to make it work, you had to use toc.oscar.aol.com port 9898 rather than the login.oscar server. Since Fire doesn't let you set the port in the preference panel for AIM, I greped on 5190 (the default port) and edited the files where it appeared. However, I don't think the files remained in a useable format because Fire no longer launched. Ah well. AIM for OS X isn't as nice, but at least it works. It's definitely a beta, but it's worth installing if your friends are all using AIM. If someone figures out how to set the port in Fire, let me know. I did find out, btw, that Fire quit supporting AIM in their newest release (0.24).
