Even the tech support people could not figure out how to get this to work. I was on the phone with them for 1 1/2 hours ( they were very nice). They admitted that I was not the only person to have a hard time with the installation of the drivers...then the soft ware...then getting the pad to work. Eventually, the tech guy just gave up...said he would have to ask an engineer (!!!!).When the tech support people can't make it work ( and tell you they are swamped with calls from other frustrated users)....you know there is something wrong.There are lots of other good options out there....so save your money and your sanity, and go with something else.
