Hi, i don't know what triggered "TheSimmer" to call me like that...However thanks very much all the others.
The problem is that, when i stop the flight with pmdg 737ngx or crash it, INSTEAD of put me on the fsx menu page with previous setting(airplane,weather,airport,time,), i see a message on my screen that windows restart the fsx from the beginning.After restart the fsx menu page has the default setting which are different from that i set earlier with pmdg 737ngx
