issues with my new Droid 2

I'm writing because I need help .........I'm having problems with my brand new Droid 2 that I have had less than a week. When I am viewing a webpage all of a sudden, when I'm not touching anything, the keyboard on the touch screen will keep flashing on and off. The only way to fix it is to shut my screen off and turn it back on. What do I do? It's getting annoying having to keep shutting the screen off!
