Periodically check MP and aircraft visibility using two computers (aircraft used in each computer requires a different
call sign for this to work).
Using 2018.3.2, checked Navion and DR400 this morning. Aircraft appeared in pilot lists and were visible to each other on apron. (Navion to Navion, Navion to DR 400, etc.).
However, when I restarted one computer using 2019.1.2, aircraft disappeared from both Pilot Lists and were no longer visible to one another.
Now thinking I'd like an interim 2018.3.3 version with Metar fixed.
