Motorola Droid X :: Home / Back Keys Double Functioning

I just got my first android phone, the droid x yesterday. Loving it so far but I've got a minor issue that drives me insane (even though it really is a non issue). I've got the volume keys on the right, and then the home and back keys at the bottom front. Whenever I click home or back, they do the home and back function, but also do volume up and volume down with every click. Its painfully annoying, because it vibrates and pops up the volume window over the top of everything, every time. And obviously, the home and back keys are two of the most clicked buttons on the phone, so its constantly going up n down. I think this also adds to battery drainage as its double functioning/working twice as much. Does anyone know of a way to disable the home lkey and back key from controlling my volume as well?
