HTC Touch Pro - Touching itself?

[kingrob76]

I've had my HTC Touch pro for about a week now, and I've been generally pleased with it. Until about 2 hours ago. Now, it's behaving as if someone/thing is continuously tapping the bottom left of the screen, as if it had a stuck key. I tried a soft reset, I've tried leaving the battery of for about 15 minutes, it still does it. It effectively renders the touch screen useless.

Has anyone seen anything like this before and have any ideas on troubleshooting / resolving it? I suspect a trip to my Verizon store is in my very near future, but I'd like to avoid that if at all possible. Thanks!
