Hi Tom,
another good report, complete with debug.txt and everything... thanks a lot!
I have never really deleted a coroute in the real FMS... not sure, but I don´t think the DELETE button would work. Conceptually it is just "triggering" a load process. Afterwards it is irrelevant... in our FMS simply type in the ORIGIN 4-letter ICAO again, this will clear the route.
In the real FMS I would simply "overwrite" the old route - enter new data, clean out the old by shortcutting (copy+paste the first waypoint of the new route+STAR+Approach and then insert it right after the last waypoint of the new SID).
You shouldnt have a crash, though, we will investigate that!
Thanks, Jan
