Dear All.

I wonder if there is anyone out there who can help. I have just bought the 707 Captain and the 727 Captain. I'm running both on Windows 7. For the 727 i'm using FSX:SE as well as the old boxed FSX version. On the 707 i'm just using the old boxed version. And in all cases for both aircraft I seem to be having one fundamental problem. My CDU will allow me to enter N and S Latitudes( keys 2 and 8 ) and their corresponding coordinates and inserting them into the left data display. But, when I try to use keys 4 and 6 to enter my Initial position for W and E nothing happens. The right data display seems to be stuck in East (E). I am able though to enter Waypoints & DME station for obtaining Aided Inertial Operations. Yes, I've read the manual but it seems a shame and all for nothing cause i'm not really going anywhere unless I can fix my initial position. I seem to be missing something here!. Does anybody knows what is going on and more importantly know how to fix this. I would be most grateful if you could help ...and I guess so would those probably many others who are having the same sort of problem.
