Whenever I hit "new posts", even if there are 4 pages, it takes me to page 1, even if I just read page 3 five minutes ago. It's quite frustrating. Is it just my 'puter?
Did it ever go to the last page when clicking on new posts? I have never used that feature, but always go to the last page or last poster if it is a topic I am following closely.
I just tried it and mine does the same as yours.
Maybe there's a trick to it like only clicking on new posts while humming the theme song to "Pirates of the Caribbean "and wearing a lucky rabbits foot.
