Random launch of Music App & Mute function while on calls

[Juju]

1. When holding the sides of my DROID2, I would inadvertently start up the Music App which would start the Party Shuffle. I disabled the Search+m in the keybinding to make sure that isn't the issue.

2. While on a phone call, while touching the sides of the DROID2 or laying it down on a desk, the phone will mute itself without notice.

Conclusion:
1. One of the touch buttons is bound to the Music App & the Mute function. I remembered a way to keybind different applications to the touch buttons but I forgot how to access it. Anyone know where I can find that info?

2. My DROID2 is malfunctioning.

3. Any other suggestions?
