Thanks for the replies. Subsequent to my post I did come across some cases where things were working correctly, but in this forum I had no way to jump to the First Unread on the http://www.flyertalk.com/forum/talkt...-5-austin.html thread when there were in fact posts I had not read. I checked one other forum and saw no First Unread links, so fell into thinking it might be a wide spread problem. Today there is a First Unread link even on the Mod Do thread in this forum. So, now I know it is not a universal or repeatable problem, but something clearly went wrong the other day.
