Apache Joystick Button Problem

[romeroom]

The joystick button on my Apache is malfunctioning and causing a lot of problems. It responds sporadically to left/right/up/down movements. The "push button" function does not work (there's no "click" anymore) and it seems to be stuck in the "down" position.

So, questions:

1. How do I disable the joystick button functionality? (I went to the Buttons utility and could not figure it out.)

2. Not having ever taken this phone apart, is it worth trying to take it apart to see if the button contacts just need cleaning or freeing up?

Thanks.
