Though some of the other applications will pan with the mouse scroll wheel, the start screen on my install will not pan with the mousewheel. I am using windows 8 Pro on a standard desktop. Purchased a laptop for my son for Christmas and it pans as intended with the mouse wheel, but my install on the desktop will not. I have installed classic shell secondarily, but I have this issue whether it is running or not. I believe at one point that I did not have this issue and the start screen did pan, but I can't pin down when it stopped. Any ideas? I have done some searching, but have yet to find an answer.
