When I plug in the apple mouse and go to mouse settings it lets me configure not only the two clickers, but all the extra buttons on my mighty mouse. However, I hate the mighty mouse scroller, so I want to switch to a new mouse. However, when I plug in the new mouse it only lets me right click, left click and scroll. My other mouse has 2 extra buttons I want to configure to open quicksilver and Expose all windows (like I had setup with my apple mouse). Can I do this with a non-apple mouse?
