Thanks for the suggestions. We have it in a nice Kiosk Case that hides all but the screen. I already have it set to never timeout, and have enabled restrictions. There is no multitask gesture (I believe it is an IPad1). I have the IP of the unit locked down, so it can only go to our solar monitoring site, but people still like to see what else they can get it to do. It often ends up on a settings screen, or on an error screen, or..???? Becasue the home button is hidden, the only way I can figure to reset it is to slide a paper clip in the tiny access hole to turn it off and back on. It gets old, especially when it happens numerous times a day. We have considered covering the whole screen with plexiglass so no one can touch it, but then if it gets turned off, we will have to open it up to get Safari back running and on the proper screen. We would also loose all the different screens on the solar monitoring site, but we are willing to sacrifice that if needed.
I was hoping there was a way to lock the IPad on just one site...
