I have used the Evoluent Mouse since 2011, now the Evoluent 4, and I was very happy with it. But last week, I have upgraded my Mac to the 10.9.5 system. Since then, I cannot auto scroll up and down and cannot go from left to right with the mouse. The Evoluent support people are not helpful really.

Has anyone had that problem, and more importantly, resolved it?

thanks
