HI, I just recently had the PMDG 777 and also the 300 ER. I have been trying to study this aircraft and it is amazing.
I usually start as cold and dark.
After everything has been set up (or so I think so), i move my controls (Saitek) and check them and they work. But as I start pushback (GSX), the controls stopped working, and I get stuck after pushback. (I also start the engine in this point)
Is there something I missed on the startup procedure that may result to this, or is this a bug?
