Question: if you draw lines on the screen in sketch mode do they
follow the pen closely, do they skip around, or are they quite far
apart in the corners? And did you really mean 75 millimeters? That's
a LONG way off. There have been a few Newtons where the touch screen
calibration degraded across the screen - quite different from jumping
all over like the jaggies. Search the archive (newtontalk.net) for
"Mike's Newts" for a discussion of those.
