Hi mac peeps, why is it so hard to have a mouse that i like? the mx revolution is alright... but i want to preserve middle click, as is possible on a windows computer.... the ability to use middle click and not toggle between the silly notched/speed scroll that seems to be set by default. is there something that is free that preserves the middle click on an mx revolution? or has logitech's drivers for mac finally been updated? thanks, r.
