Have you tried clearing the cookies and starting fresh? You can wipe all your cookies, you can delete the ones from the boards manually, or you can go to "my profile" and click "delete all cookies set by this forum." You'll have to log back in again and then update the new post indicators, but hopefully, things should work properly after that.
