A simple temporary solution to over coming the problem of the phone's screen not responding while in a cradle/dock is to plug in a wired set of headphones to act as a ground. You can also use car charger as a ground. Basically as long as you ground the phone while it's in the car cradle it will work fine. Hopefully HTC will fix this, although it's a hardware problem so they may have to recall the phones. But what do I know.....
