I've never attempted to do anything with Photoshop on a touch screen so I never realized this was an issue.. but I just got a stylus thinking it would help my work. I can't do anything with it on the canvas, though. Clicking from layer to layer, choosing a tool, and clicking on the menu options work with the stylus but as soon as I try to draw or anything else, it doesn't respond. Am I reading correctly that only certain laptops/tables work? I'm not the most tech savvy person, so easy to understand language, please!
PS. I have an ASUS flipbook and a Lenovo flip and a Mixoo sylus. It doesn't work on either laptop.
It sounds like those combination don't work. PS will work with other touchscreens and styli, such as Microsoft's Surface Pro laptops. PS will work as you described on those other touchscreens with finger gestures, so it sounds like PS, or your OS, or whatever drivers you're using isn't recognizing that what you're using is a stylus.
