content: I have had to use the touchpad type mouse for years due to a pinched nerve, causing my hand to go numb.The old one, from years ago was far, far better than this one! I guess they were bought out and the qualityis not so great. I cannot make the software work with Vista. They made a simple thing more compliacted.I wish that my old one had not worn out and it would work with Vista. Please, someone come up with a REALLYgood touchpad mouse for a P.C.
