I generally use a Mighty Mouse on my Mac. (late 2012 MBP, running Yosemite.) For Sketchup (a CAD application), I find that the Mighty Mouse is a bit unresponsive. I was advised to get an inexpensive bluetooth mouse with real buttons. I bought a cheap Logitech, which seems to work fine, but . . . If I have the Logitech software installed, it defaults the trackwheel "click" to an odd and unhelpful task. I can't find a way to change it. If I remove the Logitech software, the trackwheel "click" is defaulted to the appropriate task, but I can't get the forward/back functions to work. (Tilting the wheel right or left.) Is there something in the Mac mouse utility that would allow me to activate the trackwheel tilt settings? Or does the Mac mouse utility only allow for three functions?
