Oh, thanks for trying to help, but 2 minutes after the post I just went to: http://windowshelp.microsoft.com/communiti...us/default.mspx? and resolved the problem within 3 minutes. It has to do something with how the grouping is of the users and AIM I think. It's a pretty weird bug, but believe it or not do some searching on that site and you'll have it fixed in no time. Happy Vistaing!
