Problem with Unread Threads

[ChaosMage]

For the past couple days, every time I visit the forums it'll tell me that theres unread threads in a given forum. Thats cool. Thats good, thats what I want it to do. The problem is that when I enter the forum, all the threads appear to be read. There doesn't appear to be any problem with the forum in terms of updating the forum page in the number of replies to a thread, and its not Google Web Accelerator either, which I've been using. I disabled it, did a Control + F5 and it still didn't help. Nor did clearing my cache/cookies.

EDIT: I've attached some pictures to clarify the point. I wanted to post the entire screen shot, but it was too big. Simply take this and replicate it for every board and every thread on that board.

I've been having the same problem.

That's been happening to me for ages. Dunno what to tell you. It's an incredibly small nuisance so unless it becomes some sort of crisis I'm sure it can be handled by clicking 'mark all forums read' or something.

If you use the back button, it goes to exact page before. So if you clicked a thread from the main category directly into a thread, then hit back, it would still show it as having new threads. But if you then click the link to go to that forum, it will show it as having been already read.
