Hi all. I've had my N800 for about two weeks. Today, I was watching movies with mplayer, as I often do, and I wanted to go back to the home screen to change the screen brightness.

I held down the home key, which took me to the home screen. When I got there, my touches weren't registering in the correct locations. I also noticed that the device is registering some type of input every two seconds, opening the drop-down menu. The touchscreen is basically useless. I can't even calibrate it.

I rebooted, and the problem continued. Help!?!?

Edit: Could it be something with the buttons on the left side? D-pad and others?
