It's hard to comment. My Slice CM3 box died (suspect kids or wife plugged the wrong PSU into it) so I cannot test anything, but I never had issues with the RF remote before. It's not a general issue - else other users would be flagging the problem.
broken hardware. the device works 7/10 in the single USB port and 1/10 in the double usb port. I think the dongle is on it last legs. from the slice forums I hear nothing but back news about the remote.
thanks for the speedy reply matey.
