Well, although it WAS true that shutting down tablet.exe was fixing it, I thought before I emailed CuriousGeorgeLabs I would bring my Nvidia drivers up to current so as to avoid them telling me that. Guess what?? 66.93 updated to 71.84 and I no longer have to close down tablet.exe. I feel like a dork for not eliminating that FIRST. I should know better. Anyway, hope that helps someone else. Happy rendering.
