code of keys returned in the application window for it to work properly?

[Marco7467]

Hello everyone,

The first time I used this program, it returned me the codes of the keys or encoders used live in the black window and my actions had an effect on FS.
Now, the window remains empty (apart from the information concerning the config file used) and strangely, my actions on the buttons or the encoders no longer have any effect on the plane.
Someone could help me to tell me what's happening?
Thx
