after having created a new airframe due to 1.6.1 update, after just one flight I have an issue with fms1. For example, I press IDX, then LSK next to STATUS. The screen shows nothing except for the brackets in the bottom line. After 2-3 seconds, the message FMS NOT RESPONDING appears briefly. That happens with other functions aswell, except for DATALINK and FANS page, where the content is displayed right away.
FMS2 and 3 work just fine.
What could it be? I already tried restarting the FMS1 pulling the breaker and shutting down xplane, then reloading a flight. It stays the same.
No active failures in the failure editor either.
