Hate to be a whiner

If you use the back button then your browser runs the page from the cache which will show the old highlight. You need to do a cache refresh and sometimes hitting refresh is not enough - you need a full refresh or a cache clear out then showing the forum posts should get the browser fetching the page from the site again.

Personally I hate the default unread posts and I use a search on the latest posts instead. The crucial difference is that the unread posts drop posts you have just read so if you go into one then think ohh I know a link on that, ill do a quick search on the site get the relevant post and then go back then its dropped it for you and you cant find it again. So if you look at the unread posts, mark all as read then look at unread posts it says there are no unread posts - would you like the most recent ? Yes yes I say. So I nicked that search link and its on my sig as well cos I use that now.

Hope that helps.

BTW: Full refresh on Firefox is Ctrl F5 not just F5.
Checked here and mine fixes it with an F5 or a ctrl F5 but I have an slightly unusual internet connection anyway so YMMV.
