Since I can not post a new topic I have been directed by Captain Sim to reply to the closest topic. So, I am getting a CTD but not related to gauges. I was on a long flight and nearly 3/4 of the way complete when I got an ATC check-in messages. I replied and as soon as the Roger came back, my CTD occurred. IFR flight, no add-ons other than UTX and MyTraffic 5.4C. Any ideas, suggestions, related issues or guidance would be greatly appreciated. Not sure but it seems to be happening only when I use a C-130J. Thanks, Bob
