remote control emulation in the Orbitor doesn't work ?

[dirkcolaert]

Dear all, can anybody help me ?
I recently replaced my 8.10 installation with a 10.4. Everything is more or less working now. I do have a problem with the remote control emulation on all my orbiters. It flashes on the screen for half a second and then it disappears.
I also use a web orbiter and there it works.

Any idea ? Thanks !
