I stumbled across the announcement of an early version of Zachtek control. It worked badly on my GalliumOS3.1+chromium browser. Your new version works wonderfully well with the 80-10 Desktop Zachtek. I'm sorry that I didn't carefully log my first complaints but they're gone now. As the man said, "AMAZING!!" Kudos to Harry for his wonderful hardware, too. Tony kd1ik Lexington MA
