I tried that on a surface but the touch interface always messed up. Right under where I touched it would create a square box and I could see the desktop below it. I tried several games and all had that problem. Glad it worked for you. I returned it right after that because that was the main reason that I bought it.
I haven't experienced that problem. Were you running a fully updated Windows 8? The only one I have problems with is Arcanum. For some reason it recognizes the stylus about 6 inches away from the actual point that I am tapping.
