I'm running ichat on my macbook and my imac (both using 10.5.5) Recently on my imac i've been having trouble logging in. I contacted apple support and they asked me to delete the plist and then reinstall ichat. I did this but still had the same trouble. Then i used my installation disk and reinstalled ichat that way. I can now log and see my buddy list but whenever i go to send an IM ichat crashes. Apple support asked me to update to 10.5.6 but ichat works fine on my laptop using 10.5.5. Is anyone else having this problem?
