I just wanted to say that I was having problems today with the TFDi 717 simulation when on the HAWKZ6 arrival to KSEA. It was running smooth and flying fine.
As soon as I switched runways in the STAR page of the FMC, the aircraft started to go the opposite way. I had to take over with HDG SEL. Even if I would use DIR INT it wouldn't comply and would just show a wild nonsensical path on the ND.
I continued to try to use HDG SEL and manual decent, but P3Dv4 kept making these long pauses like it was trying to load scenery or maybe it was just confused. Then the Pilotedge app just disconnected, so I was left to make the landing to Rwy 34C offline, which went very smooth at -171FPM.
I love this 717, but I see that I can't use it for Pilotedge anymore until I figure out what is wrong with it.
I consistently get these same problems when I switch runways in the FMC and it has to recalculate the approach. I believe it is a bad bug in the aircraft. The whole thing just pukes when the runway is switched.
Oh well. Next time I'll try something that I can count on more.

Thank you,
Bob
