Does it seem to you that the pen calibration and accuracy is dependent on the application? I have the latest drivers, I have run and rerun the 100pt calibration and been meticulously careful to hold the pen the same way I write, etc. I have noticed that OneNote tends to be spot on (excuse the pun). With OneNote wherever I start writing, the ink is perfectly below the pen point. However, one of my favorite applications is PDF Annotator since I use this a lot to make notes on presentations. With PDF Annotator, it seems the point at which the ink starts drawing is offset from my pen tip by a few millimeters. Usable, yes, but extremely annoying. Thus, is it application specific or is there something else going on?
