Does anybody know if Microsoft has a Mac driver that supports the Magnifier function on their new mice? It is so hard getting this information from the Microsoft site that I finally gave up. Several of their newest mice advertise a magnifier feature, and a friend showed it to me on his pc yesterday (a wireless notebook mouse), but the mouse box did not list Mac compatability (like some Microsoft mice do). This feature would be incredibly useful to me if I can get it to work on Mac. And yes, I know about the built-in OS X magnifier function that magnifies the entire screen. This seems so much more useful because it magnifies just a square under the mouse cursor.
