This is the title of the little button beside thread titles with new messages. Trouble is that when I press it I go to not the last post I'd seen before but an indeterminate number of posts before, sometimes even before posts by me own good self. I swear I clean my cookies often enough, I don't know what this is and this is the only forum where this happens. I've been suffering this little WW2T since time immemorial. Help?
