FritsFloren,

It works a little better with some ProntoScript, but I use a separate Power page in similar situations.

On the Power page you can include whatever power commands you need. I usually include "Turn OFF Room" which will shut everything down, but I'll also include individual TV, screen, etc. power commands too. The user presses the Power button and is taken to a room appropriate page. Part of each individual power button macro is a "destination", usually the room's home page, but you can also "Browse Backward" to return to the calling page.

I'm not understanding why the Pronto would be tied up for 22 seconds after issuing a screen command. I don't see any need to wait for the screen. Obviously, the projector might cover the TV or allow the projector to splash on the wall while the screen is moving, but I don't see this as a major issue.
