One new change in Tiger that I just noticed: You can no longer be logged into the same screen name in both AOL and iChat AV. With Panther, you got a notice stating that the same SN was logged in two times. I might have iChat AV running, but then launch AOL to check my email. I could dismiss the notice with no problem. Now with Tiger, if I launch AOL and log on, iChat disconnects. And if AOL is already running while I launch iChat, I get a notice that this isn't allowed from the same IP address. Michael
