I have never had the volume stick when I use my unit. I don't think it's a software problem.

I think you have a case of sticky front-panel buttons. On my unit, the front panel doesn't line up perfectly with the electronics beneath it. As a result, the plastic button tops have to "angle" slightly to reach the holes. If the screws aren't at exactly the right tightness, my top button will stick sometimes.

This is related to the problem where the pull-out handle sometimes rubs against the edge of the faceplate. I believe that the faceplate simply needs to be cut with more "slack" in future designs. Slightly larger button holes, and slightly smaller outer dimensions to allow for more gap between the handle and the faceplate.
