Hi, can it be that with version 1.3 (FSX) at least the starting state "ON APU" is no longer correctly built up? For me, many switches are on, which should be off, but the switch for the APU, which is running, is OFF. I then completely uninstalled the whole time completely and reinstalled version 1.3, but no succes.

No need to reinstall. You can just re-save the flight with any corrections.
Moreover custom panel state setup is available via FMC.
