It seems like, in the last few days, that several of the threads I’ve finished reading still show “new” tags. It’s particularly apparent in pinned threads (which appear twice in the listings–at the top and in the body of a forum–and often aren’t indicating the same number of “new” posts in the same thread).
It’s driving me batty because I keep clicking on threads I’ve already caught up on, several times, thinking there’s a new post!
