Nice try Kris! But the car rings a bell if you leave the keys in it! And the lights come on as soon as it starts (GM). Lets face it. With all windows closed, it is only by seeing/looking for rather small details that we know a program (most of them, anyway) is still running.
Oh well, at least it doesn't hurt to double-click a programs alias when it is running. And those are usually files, so they will open a window with that action.
But thanks for the analogy, it can't hurt to try another one!
