Well, it might be my computer, but this is the second Microsoft 2004 flight sim I've purchased and the 2nd wigman joystick since I've had this new computer, and its the same problems always! It works okay for a month or two, then the same problems come back, irratic Throttle and the trim is stuck in the up position causing the airplane to stall in flight. then the problems suddenly disappear, only to return after 15 or 20 good flights, sometimes in the middle of a 2 hour flight, the whole Microsoft Flight sim will just disappear off the screen and shut off the program with no warning! I've unistalled it and put it back in the box, after 8 months of dealing with this non sence, I had it with Microsoft flight sim, XP and anything else microsoft makes![>:]
