Query: Destroys laptop pointer

I had the older version of this mouse and it worked fine for years. I would have purchased an identical mouse, but could only find this "new and improved" model. It requires version 5.0 of the Intellipoint software. Installing that softwares removed the TrackPoint software on my IBM ThinkPad X30 laptop and disabled some of the TrackPoint functions.After consulting with an IBM service technician, I found that the only solution was to return the mouse and try to find the older model. Thank goodness for the system restore feature of Windows XP.
