I have FT set to display 40 posts at a time. When I go to view http://www.flyertalk.com/forum/showthread.php?t=705857 I see up to post 159. However, on the little page thingy in the lower right hand corner, and on the thread list for the category it indicates that there should be 5 pages.

When I click on page 5, it returns me to page 4.
