Title: Finger Layout???
Review: I agree with a post just made recently. Here it is again:That is, until you realize that Logitech's idea of finger layout:Thumb: 3 side buttons2. finger: Wheel3. and 4. finger: Ball5. finger: Right buttonThank you to the poster for confirming this for me. It took me quite a while to figure this out. I wish Logitech had posted this on their site somewhere. I've been trying to get used to the mouse in various configurations. Still I swap back and forth from this one and the Logitech Trackman Marble which has always been my favorite. With it you didn't need any arm support but the Optical Trackman I think requires it.
Is the review positive or negative?
