I have the delux version and recent update. My problem is the ESC key on keyboard does not function after engine start, or after flight. No problem when using xplane.
It all worked before update. Program was purchased through Steam.
If you have game controller attached; remove that one and test.
Hmmm, every once in a while my Logitech G910 Keyboard just stops responding, the fix according to them is NOT to plug into a hub, but directly into USB 3.1 Port, so if using USB keyboard, try switching USB ports.
I have the same problem after the recent update. The Esc key does not respond, forcing me to use the Windows key to finish a flight. Mine is not the Steam version, it’s the Store version.
