Hey people.Got a new problem with 707.Put in a GPS that shows all points from star to finish of my flight plan.I plan a route in FSX say A,B,C,D,E.Save it.Move to start airport when it asks me.Load up 707.Tale off.All good.Set the onboard  Auto pilot that comes with the 707.cruise to my altitude that i want and set auto pilot,height holder and  turn knob to nav and all is sweet.Follow track past b,c and at D i land.Save flight in fsx cause i have to do something.Come back a little while later.Restart my flight.I'm still at D cause that's where I saved it.Howerer!!the flight plan is no longer there.Regardless of shutting down the aircraft before or not.If anything it only shows a trip between 2 USA airports..Never had any other aircraft do this to me in
nearly 20 years of flightsim flying.Any help or ideas would be great.Reall detracting from my like of this aircraft.
