Mouse too sensitive

Hi All...

I have installed XBMC in Ubuntu 12.10 64bit

All works great using the keyboard, but the cursor (touchpad) is too sensitive and unusable.

If I move my finger slightly on the touch pad, the cursor flies across the screen for a second then instantly returns to the centre.

I have searched for an answer and all I can find are many with the same issue...

Any help would be appreciated..

Thanks
