Logging in but keeps returning you to the log in screen?

OK, I logged off and went to log back in and it kept returning me to the log in screen.
It just happened to me. I had to reboot my laptop, problem solved.

Anyone have any other solutions?

had the similar issue yesterday
Shout box would go HIDE click on show it took me to the forum list
had to reboot to resolve

I would log in and when I tried to go to the forums I would get kicked back out, over and over.

My Fix

Now I log on and go to bottom of page and click mark as read and I stay loged in.
