While only of use to owners of Microsoft IntelliMouse (including IntelliMouse Explorer, IntelliMouse Pro, IntelliMouse Trackball, and IntelliMouse Optical), the IntelliPoint upgrade makes for an essential download if you are an IntelliMouse user currently using the IntelliPoint 1.1 or later drivers. The updated drivers provide better performance for the mouse, but most importantly, the upgrades offer Universal Scrolling.
