Hard to press Zen vision M button
I use to use a leather case for my zen and I didn't realize until it was too late that I was using excessive force to press the play/pause button. Perhaps the button sunk in a bit, but now its not as easy to press as the other buttons. Also, instead of making the sound of one smooth click, it actually makes the sound of various clicks. I'm out of the warranty, so no help for me there. Anyone have any suggestions? Is it fixable? can I make it good as new?
