I had already explained the Windows Ink problem in this topic (check it out to see what it is). I am writing now to report that today this option was automatically activated in the latest update of my Windows 10.
I don’t know if it was the Wacom program itself (Wacom Center) that activated this or if the Windows update did it… or if both did it together.
I only noticed it because when adjusting the Levels of an image, I had a lot of difficulty dragging the sliders. And also the right button on the pen didn’t work normally.
So, if you notice any problems with your Wacom, check if Windows Ink was not activated in the Wacom Center and disable it.
