I like to use the Threaded View Mode. In most cases it works correctly. There are a few threads where it refuses to work. When I go to one of the problem threads the first post will correctly be displayed but the list of posts in the upper window is blank. Pressing 'next' or 'prev' does nothing. I can, however, switch to hybrid or straight view and see all the posts. Switching back to the theaded mode produces the same faulty result.
http://www.airforums.com/forums/f318...ith-53083.html is one of the problem threads. There are others I've seen but haven't saved the link. I don't think the number or posts or length of the the thread is a factor. I have been able to view some very lengthy threads in the "threaded view" mode.
