all threads marked read
Similar issue:
I also encountered this login screen after being away from the computer for several minutes. After logging back in all threads were now marked as read. In the previous AO unread threads were still unread, even if I logged out and logged back in a day later.
I did look through the Settings area to see if there was a stay connected time limit for the site. Couldn't find anything.
Oh, Win7 64bit Home Premium, Firefox 23.0.1
Would appreciate the Admins checking on this. Thanks.
