I made one last try by going into the bios and found an option to disable the trusted computing chip. Its a brick I'll have to buy a jtag programmer and cable to fix, at 2x the nominally $100 cost of the board itself. Someday I'll come across it again and it fill make one last high trajectory flight into the trash can. Its one of the higher priced ODROID'S. The rock64 has no such bios, is a u-boot architecture, and with its different architecture can do i/o 500x faster than the pi can thru its usb-2 data pinhole. But support ranges from media only to non-existent. Changing the installed kernel questions are for a beginner at u-boot like me, either ignored on the forum, or answered by pointing at 6 year old build tools. The rock64 is almost a year from its announcement right now. We need tools to go with todays hardware, and they are not forthconing from the pine people. That, and I need someone to remove all the "am I running on a real pi3b" tests in the LinuxCNC rpspi.ko driver, then make it work with the gpio headers that come with the rock64. But this is off-topic. To get back on-topic, changing the mouse focus behavior as directed by several here, was exactly what the doctor needed, speeding up my workflow overall on the milling machine by at least 50%.
