Motorola Milestone :: Click Volume Rocker / Ringtone Gets Shut Down

I've got a couple of questions about the volume rocker: if i've got an incoming call I hear my ringtone going off, but when I click the volume rocker the ringtone gets shut down. You can imagine that's pretty annoying when the rocker gets inadvertently pressed in your pocket (since it's so sensitive), you'll practically always miss the call. when the phone is locked, the rocker is used for media volume when listening to music. This combined with the sensitivity of the button is pretty annoying as the volume keeps getting adjusted when the phone is in my pocket. Is there a solution to these problems? Can the volume rocker be disabled completely? I must add i'm probably noticing these things more because I've purchased a rather tight glove (Puro) for the phone, and the buttons get pressed rather easily.
