Samsung Focus S screen isnt working right unless plugged in?! Help? Anyone else?

I am quite pissed right now. I have been enjoying my Focus S for about two months now (bought it day it came out.) It has worked fine until toady, It seems as though the digitizer is screwed up because I can barely scroll around the OS. Its not like a laggy thing, it just doesn't consistently detect screen touches. And when I hit the power button to turn the screen off, it will turn off and then pop right back on.

Oddly, when it is plugged in it works fine! I think it has something to do with the screen time out function because when you plug it in that would be disabled, where as when it is unplugged i cant get it to sleep. Very odd. Any ideas? Anyone else have this issue?
