Thanks Ben. I hand-flew a couple of flights today with no "send to desktop" issues. I also flew a short hop with the autopilot functioning, and it seemed to work fine. Now I have to try to learn how the autopilot functions properly I did notice, however, that my Task Manager memory tracking showed about 1.7G in use when the Saab initially loaded, then about 2.8G after 30 minutes, and 4.1G after an hour--by which time the simulator was stuttering badly. Is this a "memory leak"? My other payware aircraft, including the MU-2, load in at about 1.7G and stay there no matter how long I fly. Just thought I'd bring that to your attention. I flew another flight after a system re-boot, and the Saab loaded in at 1.8G again, and 30 minutes later, was at 2.5 again--so memory loading appears cumulative. Flying with an i7, Win7 and GT660 Bill
