For me, the forum does not display unread marks correctly.
When I have read all threads and go back to the overview (and refresh) the forum still appears to have unread threads in it. I have to go into the category and open a read thread for it to work. Is that a known problem or am I the only one?

I am using Firefox 2.0 and yes, I have cookies enabled.

I randomly have the problem as well.

I usually am using IE 7 ( *gasp* )
