FMC crash when setting up arrival
-
I did a flight LOWW to LROP, created on Simbrief. Import and setting up departure went alright.
When I tried selecting an arrival into LROP, however, the FMC got stuck with a highlighted "EXEC" in the DEP/ARR page, and trying to access the LEGS page resulted in a black screen. The progress page was all empty and INOP. LNAV was apparently unaffected. I could reimport the flightplan and restore full FMC functionality, but any interaction with LROP arrivals would crash it again.
This is the first time the FMC in this plane has given me any trouble, so while it would be a cool little failure, I suspect it's a bug?
