This is for jets and Cesnas that start out in 2D mode, If it starts out in 3D cockpit mode and you don�t change your view, you�re ok. But if you change views and try to go back to 3d, it won�t, it will either go into the 2D mode and when you move your head the whole plane moves with you, Or it will go to 3D mode and freeze. Also red lights on the track IR receiver. If it starts out in 2D, you cant change to 3D and when you move your head the whole plane moves with you. Very hard to fly under those conditions.
I updated all the software and FSX is also with service pack 2. And powerful system, using win 7 64 bit.
Any help appreciated
