Weird mouse problem after replacing my keyboard
This is a bit long-winded so please bear with me... I've a Mac Pro here (about 3 years old) running Mojave. I use a Genius (i.e. PC style) keyboard and Microsoft mouse (actually, a TrackerBall). A couple of
days ago the keyboard failed and I needed to buy a new one. I managed to find another Genius k/bd but it's not the same model as last time. However when I booted up Mojave again, everything seemed okay. The monitor worked, the new k/bd worked and I could see the mouse moving.
BUT - I've now a really strange problem... Whenever I click the mouse, the horizontal co-ordinate works as expected - but vertically, no matter where I click the mouse, it seems to think I've clicked right down at the bottom of the screen :-( I can dual-boot here into Windows and Windows is still working fine.
Is there some way I can tell Mojave to re-configure / re-calibrate the mouse so that it'll work normally again?
