Hi. I am using Autodesk Sketchbook Pro 6.2.5 on a Surface Pro. I've used it before with no problems. But now, for some reason, when I touch the screen with the stylus, the marks it makes are about two inches northwest of where I'm actually touching the screen. Other than the misplacement, it follows my movements well, there aren't really any issues other than the displacement. I've recalibrated the stylus with no change. I've also tried using it in other graphics software and it works just fine. And using a mouse or trackpad in Sketchbook works fine. So it seems to just be a problem with the stylus in Sketchbook. Any ideas? Thanks in advance.
