Hi
Im using wacom Intuos. Had the same problem. Solved it by deactivating Windows ink. But i got another bug. Now When im using the pen quite often it makes a peak upwards (sometimes sideways) and moves the scene leaving a line.
Very annoing! Actually annoying enough to consider another software. I really doesnt want to so if anyone have a solution, please share!
Im from sweden so please no comments on the language. Its not mine, Im just trying to use it.
