Never saw this. You have to click the green arrow to go to the latest post if you're clicking from inside a sub forum or on the sidebar, but if you click from the main page of the site it will do it automatically if there's a new post you haven't seen.

When I click from the main page it takes me directly to the latest post and skips any I hadn't already seen, which is annoying.
