I keep getting logged out.

I thought it was from opening new tabs in IE 7, but I stopped doing that. Now it's happened again, and all I've been doing is using the "Back" arrow/button or going back by selecting one of my recent pages. Again, Win XP Pro and IE 7.blah.blah.

Of course, it could be my old, crappy computer, but it doesn't happen on other sites.

Did it just start happening? Because I haven't changed anything in the login/cookie code in months.

I DLed four updates on the 13th. Seems like it started after that.

The updates were: KB 923694, KB 926255, KB 923689, and one for Windows Media Player.

Here's a link describing what they're for: http://www.microsoft.com/technet/security/current.aspx

Hope that helps.

I just got the log out thing.

I was deleting everyone from my favorite's list, and about every third person it would come up with a page that said "invalid login".

Hasn't happened while using FireFox, BTW.
