hey everybody. I've had the canvas for a few months and I really like it, but as of late the pen cursor has been sticking and disappearing while I'm drawing, it'll actually become totally unresponsive to the pen for what seems like longer and longer moments. It does it in every software I've tried, even occasionally in my web browser. I updated a bunch of drivers and deleted the windows calibration files in case their was a conflict, but it's still doing it. Anybody have a similar problem?
