Hi - I've just bought a MS Natural Wireless Laser mouse. I haven't installed the Intellipoint 6.1 software which came with it, but am using the 5.3 version (there are reviews on Amazon which suggested using this as 6.1 isn't compatible with photoshop).
Does anyone know if 6.1 is required for the 4 way scrolling? I can only get the tilt wheel to go up and down.
I have a similar mouse, though mine is Logitech, to operate horizontal scrolling I press the scroll-wheel down (like a button), then on a web-page a four-way arrow appears, allowing vertical and horizontal scrolling.
