SerraAva,
Thanks. Great suggestion on the initial blank scene. I'll give it a shot. That might just be the trick to get around the scenes staying up together as well (the last question), although I still hope to get some additional info on that functionality.
I hadn't thought of keeping some lights off the show. I think I have a bad habit of always keeping units selected, even when not active, and that's probably made me think I couldn't. I'll try keeping some units off and manually working them.
Thanks again!
Chris
