Okay, this is really annoying, after reading threads, when I go back, NO NOT BACK WITH THE <- key, just by clicking the link, I still see them as undread, anyone having this issue?

yea, on threads with polls, they stay marked as unread

I get general fucked-upishness when it comes to which threads are marked as unread. Sometimes when I browse the forums, ALL of the threads get marked as read - even the ones I haven't looked at yet. :cry:

Happens to me too. I think it's usually after I click "Index" link.
Like now, there's a thread in Server talk that is marked as unread, but
1) on the Index page the Server talk is marked as read
2) I've read that thread already
Refreshed all the pages (index, server talk, thread) many times, doesn't help.

punBB is fucked up with regard to this. Try using the 'mark all as read' link on the main forum index.
