I've had my SP3 since September and have rarely used the pen. What little I have, using the handwriting panel in combination with OneNote 2013 worked pretty well. I've used it hardly at all while working with the Windows 10 Technical Preview. Now I've upgraded to Win10, and the handwriting panel is different. There's no button to accept the input, beyond acknowledging the autocorrect suggestion or the Enter button. And I can't seem to select a place on the page where I want my input to start. Finally, for every pen stroke I make on the screen, I can see the little lines and boxes the system is using to (I think) help recognize the letters. This happens in both OneNote 2013 and OneNote MUI. I have re-paired, then uninstalled the drivers and re-installed. No change. Inking works fine, but I have a weekend workshop coming up in October and inking is not what I want to do. Am I doing something wrong, or is this just part of Windows 10 that isn't quite right on the Surface yet? Is there a comprehensive source of information on using the pen and the handwriting panel that I've missed somewhere?
