I've noticed a thread of mine 'disappears', I've got my display prefs set to show 10 threads at a time. My thread happened to be at number 11 but when I moved to the second page it wasn't there. Could this sticky topic be blotting it out? Increasing the displayed posts to 15 shows my thread at a posiition 11 on page 1. Is this a fault or a 'feature'?
