1. Many years ago Knegel modified the code to activate or de-activate features based on difficulty level. These included cockpit toggle and external views. I think padlocking was also included but I do not use it so I cannot tell for sure.
If you go to Game-Setup, difficulty and select Combat level you have the choice of "Green", "Veteran" or "Ace". With "Green" you should find that everything is enabled.
2. Alt-Q will exit the game in multiplayer. Alternatively you can hold the Esc down for several seconds
3. Windows 7 runs EAW as you describe.
I do not get those issues in Win 10, but I prefer Win 7 because it gives me a better frame rate, so I put up with those inconveniences.
