I have windows 7. But on all my friends XP Pc's with ESET installed. Windows Live Messenger doesn't sign in automaticly during start up of the PC. This is caused by the start up scan. I know this is not a 100% Beta issue. But thought I'd mention it as I hoped it would have been fixed in the Beta. But no luck. It's not a major issue but something like this should just work? Maybe you guys can have a look at this please.
