This is one of the features on this forum I use a lot, but sometimes it doesn't seem to get me to the first unread post of the thread. Instead it takes me further ahead. I don't know exactly why this is happening. It seems to happen more in threads with several pages or with polls, or both. Maybe posts are being marked as read, even when you’re not reading the thread but you’re logged on or maybe they are being marked as read when you are logging out, even if you stayed away from that thread that time. Hope this helps sorting it out.
