Ok I found the "hold-the-home-key" method of seeing my "recent" apps. And I have Advanced Task Killer, so I can STOP apps. But this is obviously not the way things are supposed to work, right?

I use the browser. I'm done with it. How do I CLOSE it?

And why is it that every time I open Advanced Task Killer, Pandora is running again? I go in, kill it, go back to the home menu. Go back to Advanced Task Killer, and there's Pandora again!

If Pandora is running, what command or keystroke do I use to "switch" to the RUNNING Pandora? (or any other running program)

Thanks!
