The forum would not accept the image at its original size - upping the maximum file size would be very helpful for this sort of thing.
The limit is 4MB per attachment, I'm sure if you use .jpeg, even 4K screenshots should fit in that size.
What else can we try to stop the menu popping up and then immediately disappearing again after I park up, so that I can deboard passengers at the end of the flight?
The fix I posted should prevent the menu to be closed by other add-ons or some hardware to send keys
other than the numbers 0-9 to confuse the menu system, but if either an hardware or another add-on is sending key
from 0 to 9, how GSX can possibly know it's you or something else pressing the keys it expects to be pressed ?
Of course, that's just a theory, if you sent another log after you made the fix I suggested, I might be able to confirm it.
