When I go to the flyertalk miles forums all the new posts since my last visit have the yellow icon lit up. I go to the threads and the new posts have yellow folders. I then read a thread and when I hit the back button all the yellow icons are gone. It is like I refreshed the page instead of just going back. This started happening on Sunday. I have been reading flyertalk for several years and haven't encountered this problem before. I am not computer savvy and would appreciate any help you can give me. Thanks.
