I try to save during a flight and understood here and there that I have to press ESC and then the option ‘space load/save’ should appear next to ‘Resume’, but it is not there.
How can I save the flight now?
Do you see the icons and the text RESUME and RESTART and MAIN MENU? or is the bottum bar disappeared? If so, press ALT+ENTER to get into full screen
Thanks, I discovered what is happening.
I was flying a bushtrip and then this option is disabled. There you have to complete a leg to pause and continue another time.
The option is enabled during a normal flight. I tested it and works fine 
Happy User again. Safe landings
