Hi, I just purchased a Logitech Marathon Mouse M705. Unfortunately the software that came with it is only compatible with 10.5 Leopard. So, is there any Mac software that lets you assign keystrokes, scripts, and/or apps to the mouse buttons? I already used The SysPref Expose Pane, but all apps, dash, desk, app windows, and view all spaces isn't enough! Is there a way to switch spaces with the side-buttons on my mouse w/o zooming out to view all the rectangles?
