Retropie in OSMC - Back to retropie menu from game not working

Hi,

first of all sorry for my english.

I have installed retropie in osmc and it is working ok but just one thing is not “working”. When I am in a rom, I can not come back to the RETROPIE menu, I have to restart my raspberry pi 2.

I have read that this “come back” is by pressing START + SELECT in the xbox wireless controller (previously configures, of course) but does nothing in my case.

I also have configured my keyboard with the xbox-360-pad key-mapping. I have selected key ‘9’ for START and key ‘0’ for SELECT, but the same result.

Any idea?

Thanks
