My young daughter is bewildered as her ipod has a problem she can't seem to fix. On the home screen (the one that has all the apps listed) the size of the app icons appear to have suddenly gone to 2-3 times their normal size. So has everything on the ipod - in all games and apps everything is 2-3 times normal size.

She says it just suddenly happened in an app, doesn't think she did anything.

How can she fix this? - she has tried the thing where you put two finger tips on the screen and close them together to shrink the screen. Doesn't seem to work though......any thoughts?
