I've used beta versions of LightJockey for years and haven't had problems, except for one build. I've been playing with it for a couple hours. One thing I've noticed is that it is very slow on computers with multiple user accounts. I plan to download it to my notebook later and try it there. Trouble is, I likely will never get to use it in real life. One place I know of had a hardware maxxyz and ended up selling it because it never got rented. All their customers know Hogs, and would rather have used one of those because they had already mastered them, as opposed to learning something new.
