It's done that at any airport, not just a few...., of course, I don't always stop during my taxi to gate. Most recently, landed KSFO (Flightbeam) and stopped as I normally do after exiting runway to do after landing stuff and set up GSX for my gate F81. I start to taxi from Tango to Bravo and stop at B3 before entering the ramp. At that point, GSX thinks I'm parked and gives message to shut down engines. I check my AFCADs and with Simple Airport Scanner and have no duplicates.
If you are saying GSX should not respond to a stop before parking as a stop for parking then okay, I thought I was reporting a minor bug that does not normally arise because we usually don't stop enroute to gate. If it is a minor bug then I'll accept your thanks. Either way, I'm moving on.
