It now keeps New Posts until you log out. They are still in order from newest to oldest -- so you simply stop when you're out of time.
But it shows you what's been updated most recently.
What was annoying before -- if you let CathInfo sit idle for 1/2 hour, it would log you out, or at least update your New Posts, so that there would be NONE.
Some people like to go through ALL the new posts before it resets.
Later on, I might add a "Ok, I read them all. Please reset" button on the New Posts page.
