Yes the only way to have a menu when I press Shift f FSX then ground service menu appears.
That's what I said: it means GSX is working correctly, but you cannot use its default key, because another addon has already taken it. Which is why, you can configure GSX to use another key. But again, what's wrong with using Shift+F ?
J have tried several key and nothing fonctionne.j have natural sky next.fiber acceleration, map g v3.12. fs copilot, airport desing editor and FSDS.
Again, that's nothing to do with GSX, it's just that you still haven't found a free key. Try something using TAB, like TAB+F12, for example.
