Hello everyone!
Although normally only questions are asked here, I come up with an answer...
For folks who want to make a really 100%-situation-reproduction (for a longer term break) I yesterday tried a simple trick:
I paused FSX (by pressing "p"), exited full screen mode, minimized FSX, (waited a while for sufficient post cooling), from WIN7 chose hibernation.
My Laptop entered hibernation... On "wake up" everything was as before:
I maximized FSX, set full screen mode and on pressing "p" the GSX catering guys kept on walking on their lorry ramps.
This is the best level of fsx-state-reproduction I have ever accomplished.
I hope you can make use of it for your flight interruptions enabling "PC hibernation".
Greetings,
Claus
P.S.: I have only tried it with the PMDG 737 NGX, but it might also be of great use for the B777 on long hauls...
