Every time I’m notified of new posts in the Welcome to BBS thread, clicking on the blue circle takes me to this post from last month. In addition, the blue circle usually indicates the wrong number of new posts. Today I saw a 3 when there was only 1 new post. So far I’ve only noticed the blue circle count be incorrect on that topic.
And while I’m here… from time to time the Unread indicator tells me there’s one more tracked topic with new posts than there really is. So I’ll visit the main page, see Unread (3), click on that, and find only two tracked topics waiting for me.
Edit: Just to note, this is with Firefox 22 on Windows 7.
