@Mark Hi, Turned off state saving, I found no key binding, on 3rd try the plane turn on normally and it was a pleasure to fly (Berlin to Copenhagen landing RWY 30 in full ILS). State saving acts strange , I turned off the plane all knobs and switches turned off but when starting half of them were on. Will try to see if I can outline precisely the problem for you to investigate. Thank you for the reply. You are a wonderful team I love you r products.
