Hey Doc,
I think more testing is either currently in progress or needs to happen, I just signed in as Grainger. Happened three times until I went to the products page and re-entered the forum.
I've been a couple people so far (Grainger, BTRancho, Brent. I think it may be limited to people who are currently online). It seems to have chilled out now without doing anything. That's Heisenberg for ya!
I've had this twice today, once in work, and again just now on my home machine. In both cases i was logged in as somebody else and had to logoff/logon to correct it.
