Is everyone sitting down? After successfully getting into my UBB.threads board on IE and not getting into this board through another tab in the same IE 8.0 session, I closed IE 8.0 and all the tabs and started up IE 8.0 again.
Voilà! I am posting this from an IE 8.0 session. I'm sure everyone must think I am some crazy poster. It seems like others may have had a similar problem, but I almost think I am nuts now!
