Return to main menu not working when HDMI cable is plugged in

HI there - when PM arrived i plugged my sky mini box in everything was fine - i could flick between the sky box and the main menu on the pico with no problem - now the menu button does not work and i have to keep un plugging the HDMI cable to get to the PM main menu - anyone else having this issue?
