Ulrich,
In the pictures in post #400: You are not selecting a 2D-window, but a camera-view !!!
To open/close a 2D-window, you should use menu "Sichten - Instrumentenbrett" ; as with any other aircraft.

PS:
Reasons why Shift+2 or Shift+3 might not work to toggle 2D-windows:
1. Caps-Lock is ON (should be OFF)
2. You have changed the default keyboard settings for "Select-1", "Select-2", etc ...
3. You are using digits 2 and 3 on the Num-section of the keyboard. DON'T. Use digits 2 and 3 on the main keyboard section.
