power off and app restart

[Han]

The START() function of an app is called only when switching to that app. Once you've already switched to the app, I don't think START() is ever called again. Powering on the calculator does not restart the app if you're already "in" the app. It simply ensures that all running subroutines are exited (i.e. you're back at the home/cas screen, or one of its default screens like a plot view) and then powers off. You're still "in" the app, though.
