I have noticed recently the New Posts list not working correctly. Right now for example the thread titled, 'Kernel memory leaking' Intel processor design flaw forces Linux, Windows redesign has vanished from the list. Edit: But when I pull up the recent activity list, it is right there where it should be.
If you are visiting a thread it disappears from "New Posts", but it should re-appear if a new post has been made in the thread after your last visit.
Yes I know but there were lots of new posts added to it and yet it wasn't in the new posts list. I deleted my browser catch and today its back to normal.
