I know that you can delete a movie from an iPod Touch by swiping the title, then tapping the delete. Is there a way to set the system preferences to prevent this from happening. I teach children with various handicapping conditions, and use an iPod and iPod touch often with my students. They occasionally will (because they do not have great dexterity) swipe instead of tapping to select a podcast or movie that I have created for instruction. Any advice would be great.
