I am most familiar with Wacom tablets. They have a touch/gesture feature on/off switch build in.
But maybe we need to do a switch. We haven’t come to gestures yet. It’s on our todo list.
I was thinking, maybe you would benefit from having AP running with Windows Ink? You could try it and see if it changes anything for the better. Do this:
Find the file “qt.conf” (probably here C:\Program Files\Animation Paper\qt.conf). Rename it to whatever – to save it, if you need to restore. Then launch Animation Paper again. That forces AP to use Ink.
Let me know if that helped with anything.
