Whioe flying the 767 and I go from normal windows to 3d mode, the throttle drops to nothing, and with time build back up...I usually lose airspeed until the throttle goes back up to full..does this happen to anyone else?

Affirmative on that issue! Regards ;-)

Does anyone know a way to fix it???

Nope, not anything else than try to stay away from changing windows. Maybe someone else has some good suggestions?It's not really that big a problem. Speed is recovered in almost no time. Unless you are in some critical phase of the flight. But that's usually not the case, at least not for me. ;-)Regards

I think this problem was solved in the v1.3 patch, but I would only recomend this update to anyone with a third party controller like the aerosoft MCP as there are other issues with v1.3, that have caused prople to revert to V1.2 patch.As stated this does not really cause a problem, two methods to correct and get airspeed back are:1. hit TOGA on the TMC2. Change to a clb function if in the crz, on the TMCHowever the loss of airspeed can be serious if you have a strong tailwind, as it can cause the wing to stall. (I think this is called the alpha floor in the airbus, but I am not sure)Cheers, Chris

i disable the AT!
