>It seems anonymous access created new problem. I opened Firefox today and wasn't ask for login. It seems UT recognizes me as logged in because I can create a reply to you but left and right panels are blank. See attached screenshot.

I see an error occurred on that one. This is why it blanked it out.

Yes, once you got back in Firefox today, you probably had the old interface. With the new one, you would now see "Logged in as anonymous" which would confirm that another login expired that current session.
