when I have arrived at the gate I cannot open the menu with the different options as "deboarding" "catering services" " pushback "and so on.
Your message is not very clear. Do you mean:
- You see the menu, but it's too small to show the GSX options. This is easily fixed by resizing it with the mouse.
- You see the wrong menu, the one that asks to select a parking, when you think you *are* in a parking. This is caused by a scenery conflict.
- You don't see any menu open. This is usually caused by GSX not loading, because of a faulty antivirus. But if this is the case, it should happen with every airplane.
