OK - That’s weird. The symptoms of the last visited timer reseting (which I wish you guys would do something about!) definitely seem to have changed slightly.
I first noticed this a couple of weeks ago or so (I forget exactly when) but at the time thought maybe I had just had a brain fart and wasn’t paying attention. This time I know it happened. I got on SDMB, and noticed my last visited time was yesterday at 07:00 PM. Played around for a few minutes and my last visited timer reset (accompanied by profanities from me) to 12:54 PM today, i.e. the current time, and SDMB thought everything was read. Played around some more and it fixed itself, going back to yesterday at 07:00 PM and more recent threads went back to being unread.
Huh?!
