I too would like to thank Rob for keeping us informed. I don't know if I'd do the same given the circumstances. Anyway, I like Vue's approach a lot. It has very unobtrusive on-screen trackball and sliders for manipulating cameras, lights, props, etc. It also allows numerical entry for same. And, what I like best, you can also grab the object in any view screen and manually move, rotate, or scale it. Vue's controls are incredibly easy to use, IMO.
