I've done that to one very highly rated raspi killer. No place in the 
propaganda did it mention it had a UEFI bios. 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%. Thank you to all that responded.
