Thanks, but I have no problem with dragging and rotating objects. It's changing the plan view with my touch pad that's whacko.

To clarify: two-finger-drag scrolls the plan view horizontally or vertically, but moves about 1/10 of the view with each tiny motion (way, way too much). And command-two-finger-drag zooms about 1% with each tiny motion (better, but still too much).
