My surface is only two weeks old and have loved it. Noticed tonight thought that I have a dead zone in the touch. Mouse and pen work in this area but the finger touch does not work. I have reset the calibration and re- calibrated. If I have to refresh I am going to be upset as I should not have to do that on a two week old device. The searching I did was all a few months old so I am hoping there is a fix for this.
