Ultrafast Scrolling

Yesterday I finally bought a new computer mouse. One with an ultrafast scrolling wheel. Arriving in my CAD-Software of choice, Rhino3D, I tested it. I zoomed out, and back in, but hey, where is my model?

I had been using Rhino for six years and this had never happened to me. I had to go to a beginners forum to figure out how to find my model again.
