You were clear and my reply still stands.

Most likely MC reads input from stdin, but when launched from the panel
which is spawned from the session, the process has no way to read stdin.

When that occurs, try switching to a console and kill the process of MC to
see whether that restores the input in Xorg.

Alternatively, just enable "[x] Run in terminal" in your launcher so that
MC (which is a text based application) can run in a terminal.

Cheers
Olivier
