Is Input.Touch off on Windows Surface Pro 2?

I’ve seen some other similar questions on here regarding the editor and Pen/Touch being off but my question is about the actual stand alone Unity build for Windows Store. We’re using NGUI as our input manager (which calls on Unity’s Input.touch), but for some reason the touches on Windows Surface Pro 2 are off by about a third of the screen as if the touch area was smaller than the actual screen size. The touch works fine on all other Windows Store devices including Windows Surface Pro 1. Any idea why this might be happening would be greatly appreciated!

The Answer was on the Unity Forums stickied under windows development:

If you’re experiencing touches returning incorrect positions, please do the following:
