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.

I had a friend who tried to install Trisquel Ubuntu on a new Toshiba
laptop, but wasn't familiar with the newer UEFI, and thus turned her
machine into a brick. Still no luck unlocking or resuscitating it,
last I heard.
Bill Beware of UEFI/EFI ... don't know if your
devices have such new
"features", as it was hard for me to keep track of the different
devices, the various issues, and their place in your own scheme of
things. But if you try to install a Linux system on a newer
machine that has UEFI, it will "protect" you from the dangers of
Linux and hackers. There are ways to disable UEFI, though.
Like anything, to use it safely some (re-)education is involved,
getting the hang of new paradigms. I have two UEFI PCs. When I
started composing this I was doing my 7th (multiboot, adding OS #3
to an M.2 device) installation in UEFI mode, *buntu 18.04, to become
Tubuntu, to follow-up on a year-old, still open TDE bug, but it's
already finished and rebooted.
