I did a search on Windows Vista operating system and Fedex and found no previously reported issues with trying to open the J/S page from the Fedex Flight Ops website. Using Internet Explorer 7.0, same as what I was using Windows XP with all the same security and privacy settings. What I get when I open the page is the "enable javascript and accept all cookies". I have this set that way and still no worky.
Anyone run into this?
