We have done sort of a crude hack possibility to make it compatible with Windows Ink. But I’m not sure it is preferred, because as far as I know it introduces various side effects. However, why not just try it, right?
Go to the folder where the Animation Paper exe file is located (probably c/programfiles/animationpaper). Find the qt.conf file. Remove it, or better, just rename it, so you can always get it back. Then restart Animation Paper.
Let me know if that helps or not. 🙂
