Steve,
I had to turn off the motion sensor feature because mine did similar. It was so sensitive it would seem to come on when the air conditioner would blow on it. It seemed so sensitive that it would come on when I would walk too close to it LOL.

Press and hold the "main" button until the remote menu comes up then turn off the "pickup" option and see if that helps. Don't go near the factory reset button though.

I have also been told that doing the factory reset button then load a blank rcc file followed by your working rcc file will fix many problems created by software errors in the remote.
