3 times now while using Safari (may not like 10.2.4?) I will looe the ability to scroll with my mouse. Then seconds later I will lose the click ability from my mouse. My mouse still has focus and move across the screen, but i can't click anything. The workaround was to unplug and re-plug the mouse.
So it's 10.2.4 related to eitehr Safari, USB mice or the Logitech software.
Anyone experience this?
