Tilt Wheel That Won't

Hi All

Just got a M$ Wireless mouse with a tilt wheel.

Firstly the wheel works for un and down but does scroll left to right as it should. But my main problem is that on my old mouse I could move backwards and forwards on webpages with the extra buttons on the mouse. Is there anyway I can get this tilt wheel to do the same.

Maybe you can program the mouse from somewhere but I really can't work it out.

Any help would be great.

Thanks

Alex
