Yeah, ok, I don't know why it's doing this either. And it's not operating system dependent, though Vista does seem to have more issues with it than XP does. I log in and can stay remembered for forever on either of my laptops (Vista & XP), but no matter how T logs in, it never remember him. (really that's assinine of it if you think about it... not remembering your boss? ouch...) T hasn't had to change his password the 40x I have had to, so it really isn't a password issue... T's also doesn't refresh the Library pages correctly, but that's a Vista issue.

In any case, clearing the Library cookies is different than clearing the browser cookies. If you clear one and not the other, your computer sometimes does creepy stuff and keeps you logged in on some sites and not on others. Also, when IE updates itself, it sometimes installs patches for cookie issues, so although you may still be using same browser & settings, it isn't the same monster.

Keep fiddling around with the stuff... at some point there might be something that works.
