I just got my ZenBook Duo UX582 and was under the impression I could set up the ScreenPad Plus as a drawing tablet for Photoshop, the way a Wacom works, but it seems like I have to drag the photoshop window down tot he screenpad and work on it all there. I am used to my Wacom tablet that is not a screen tablet and an old fashioned drawing tablet. Is there something I am missing? I just want the ScreenPad to be a dumb drawing tablet and not "draw on the image" down there as the brightness is not as good as the main laptop screen. I want to use the pen on the ScreenPad and have the image be on the main screen.
