@JoAnne65 you can put the walls up and down in 3 with the End and Home keys.
And I absolutely hate the TS4 camera. I use the TS3 camera in 4 and I still feel like I'm doing nothing the whole time I'm playing except fighting with the camera to see my sims. It's like the mouse just refuses to control that camera. :/
Apparently with TS4 there is no persistent state saved anywhere in the game. I read a guru say something to the effect that when you go back to live mode, the game is supposed to be calculating what the sims would be doing (instead of saving them exactly as they were). This was a reply in response to sims always standing on the sidewalk when players went back to the household (something was obviously going wrong with the calculations!).
