hmmm,

this is sounding a little familiar. i had a touch screen problem last week. it appeared that the whole top edge of the screen (where the window manager elements are) became unresponsive. I updated to PR1.3 and the issue went away (apart from a little blip later that evening).

My question is this, though: does flashing affect the warranty? do you need to be using the NSU to maintain the warranty?
