iChat in Zeph 10.5.2 Rev.2 is pretty much unusable except for seeing who is online. I can't message anyone, and when I go to Preferences/Messages the chat bubbles are missing and everything is just not working. I double click on a contact and I get the chat window but it's not actually for anyone, it is blank. And every other time it crashes iChat when I double click on a contact. It used to work on previous installs. And the only thing I changed was I got a new video card, (8800GT 512mb, working using EFI string) and reinstalled fresh. I have all the updates installed but the 10.5.3 update. I am using the 9.3.0 kernel, default SMBIOS that came with the DVD.
