I think that my Center Button has a short in it.

When the Center Button is pressed, it sometimes/randomly causes the screen to start scrolling rapidly vertically. The only way to stop the scrolling is to hold/mush down the Center Button until it interrupts the scrolling.

Well then, just don't press the Center Button and use Advanced Gestures, right? That helps but the button still gets pressed sometimes by mistake or going in/out of the holder.

Any ideas for a work around? Maybe a way of disabling it?

No insurance; Out of warranty; No big deal there. I could just buy a replacement on eBay but would like to squeeze a little more life out of this one until Sprint releases Pre2
