I have resolved this by resizing the window which opens when you open GSX with Ctrl-F12. It does not appear to be a problem with P3Dv4.2
The OP reported TWO problems:
- The automatic choice of options, which IS a P3D4.2 bug
- The Simconnect menu windows too small to show all the entries, which is NOT a P3D 4.2 specific bug but, instead, has been there for a long while, and it seems to be caused by some unusual ways some 3rd party developers create their gauge panels, which confuse the sim into calculating a too small size for the Simconnect menu window.
