Does this happen to anyone else?
I log in.  Top message changes to Hey, Tiger-Heli, you have 0 messages.  I select a forum.  Top message changes to "Welcome guest, please log-in or register".
Cycle repeats.
This happens mostly in Opera, although it happened to me in IE last night also.  Doesn't happen on my NT machine in IE (obviously as I am posting this).
Any advice or suggestions.
I know Opera's cookie handling is miserable, but I never had a problem with IE before.
