iChat after Lion–Messaging Agent keeps…: Apple Support Communities

Thanks paige.findley!

good news: found the following solution

Navigate to ‘/Users//Library/Preferences’ and delete all com.apple.iChat* files. You must then log out for the fix to work and re-setup iChat the next time you log in. I’m pleased to report this solution does work and I can now open and close iChat without having to reenter my passwords each time it starts up.

the above solution is from http://www.selikoff.net/2011/07/20/apple-os-x-lion-review/
