No ideas here. Mine was doing the same thin a couple of hours ago, then everything worked properly, and now it's back to having to click the back button three times to go back to the previous page.
I will investigate my firewall log, but I don't think that's it. When I leave my cursor on the back button it gives me a very weird Back To: address. Then, when I put it over the forward button, I get a Back To: "HTTP 404 Not Found" address.
Also, when I navigate to other sites, like NWA.com, or MSN.com, I can go back and forward with no problems using these buttons. This leads me to suspect that something ain't right at FT--not that I'm complaining.
Very strange. Hope this helps.
