I noticed that the notes panel that can be brought up from anywhere via Ctrl+N, can indeed be brought up from anywhere, including the notes panel. It's possible to press the hotkey multiple times, and have to close the menu multiple times as a result. It might be a good idea to disable the keyboard shortcut when it's already open.
Done.
I'll take this opportunity to mention a different issue: whenever I try to type "ń" in the game, it opens notes instead...X-Com is not a game where you do lots of typing, but still it's not very nice that I can't type a name with "ń" in it.
It works fine for me.Do you have to press CTRL when typing ń on your keyboard?
right-Alt could be aliased to Alt+Ctrl on Polish keyboard
What does it mean?
