After photoshop started and once it get focus, I can move stylus to low part of the screen. But if I switch to other app's windows, stylus can be moved to full screen.
I found a similar case on yotube, but with gimp, it can work although looks like wierd, and can be worked around by hide mouse cusor. The video is Issue with Gimp and Intuos4
With photoshop and painter, I have no luck. Do you know the solution? Any guide will be appreciated.
