My iPad has so many apps running. Double clicking the home button shows them. Powering off doesn't close them like I was expecting. This is what I did:
1. Hold the power button, then " slide to cancel" to shut it down
2. Press and hold the power button, then let go to boot it back up
3. Watch the Apple icon for a few seconds, then slide to start
4. Double click the home button, and all my apps are still there
I upgraded the OS last week, is this normal behavour now? Is there a way to close all apps at once?
