I like v. 4 beta more than v. 3, but I noticed that in v. 4, when you zoom using the mouse's scroll wheel, it does not zoom in or out smoothly. Instead, it zooms in/out in inconsistent amounts, in a unsmooth way. The same thing happend when I pan by clicking and dragging. Is there anyway to fix this in preferences or something, or is this just how Google Earth v. 4 beta runs?
