I use my iPad 3 in work and in play. Have 64 gig wifi, with 260 apps. Too often, I'll try to start an app and it starts, some, then stops and kicks me to home screen. Weirdly, it doesn't happen to every app (some will start), but it happens to many apps, maybe mostly ones in folders. What usually fixes it is to get any old app and install it. But then eventually it starts up again, like now.
Any idea why some apps freeze and take me to home page? Any fixes?
