I installed Windows 8.1 enterprise on my Dell Inspiron 17R yesterday. Everything seems to be working great, except for one thing. I just noticed that pinch to zoom is no longer working via the touchpad. I came to rely on this feature quite a bit when running Windows 7. There are no issues in device manager, but under Mice it shows PS/2 compatible mouse instead of Synaptics touchpad. Any idea how to correct this and get my pinch to zoom back. Thanks!
