I got a Logitec NK 540 keyboard and mouse, and I love them! Problem is apparently solved. Thank you so much.
Cool! Happy it’s resolved. I’ve since discovered that this is a known issue with the Logitech mouse. It double clicks without notice. I think it just wears out. If you are so inclined, here is a video on the repair. https://www.youtube.com/watch?time_continue=294&v=V66Cd2Y4IPs
