When I logged in today, sometimes when I clicked the [NEW] button next to a thread, when I have left that thread it still showed up as having new unread posts, even if the last post was hours ago. If I click the [NEW] button again, instead of getting a notice telling me that there haven't been any new posts, it takes back to whatever the first new post was.
Is this a problem that other users are getting, or is it because I have a slow Internet connection?
It happens to me too. Threads still show up as new even if I've already checked them, not sure if it's a problem or not. No big deal. I usually click the user's name to the far right and that usually takes me to the latest post.
I made some changes to the server configuration last night which might have affected your sessions. Clear your cookies, or sign out and then back in again.
