I am running Sketchbook Express on Windows 8, and experiencing troubles with my touch responsiveness. It happens with my graphics tablet and touch screen. I can click any of the buttons on the screen perfectly fine, change options, move bars around, etc. But whenever I draw on the space, there is roughly a two inch gap between my finger or pen and the line that is actually drawn. I can draw fine with a mouse, though. Anyone else had similar problems? I can't seem to find anything on it. It was working perfectly, and I really liked the program, but it all of a sudden stopped.
