Back to menu ???

[spidersky]

Hello, I acquired 1946 on the GOG site, it works correctly with win 10.
But I meet the problem when I finished a mission, I don't know how to return to the menu.
Could you help me and tell me which key brings me back to this menu?
Thank you in advance for your answers.
