Hi Dave,
In this specific case I turned off the taxiway onto the apron and I must have been immediately within 50 meters of the gate already so not sure which of the two gates ahead of me I was suppose to go to.
The error messages always seem to come up behind other windows that are open on the screen. I always have the key press window, the closed caption window, and the screen that shows all ATC commands to me open. I didn't see the error window until I closed the other windows at the end of my flight so I don't know when the message came up. I don't recall, however I may have closed FSX prior to closing PF3 at the end of my flight. Would that generate an error?
Dave
