I used a follow me truck to guide my PMDG 737-800 to its parking spot at FlightBeam's KPHX (Phoenix) airport. The marshal guided me in. But once stopped, wheel chocks in place, parking brake on, jetway in place and doors open, I was unable to pull up the GSX menu with CTRL-F12. Everything worked well at the departure airport, but not here.
I noticed that the arrow cursur in FSX turned to a pointer finger when I hit CTRL-F12, which I found unusual.
What might I b e doing improperly?
