Thanks bcswan, I tried recalibrating a few times and the handwriting looks a lot less like a 10-year-old's now, but the screen still seems to be unresponsive in spots. The header through the first line (in lined journal/note paper mode) and from halfway through the 9th line to the 12th don't respond to the stylus. This is true for even the pop-up menus. i tried using the space maker tool option and was able to move scribbles into the unwritable area, but then I was unable to reselect the pencil or spot eraser from the tool menu since they fell into that same unresponsive area of the screen. I had to use the pencil icon at the top to get the pencil tool back. Any other suggestions?
