alice-teacher Alice 2 "While the world is running" event

[Vanderhyde, James]

I agree with Bob. Just catching the exception before the user sees it would be a good enough fix. You could have an Alice alert (instead of a Queen alert) that says something to the effect of “The action at the end of the While the world is running event was not run, because the world has stopped.” Then it is not a silent fail, so the user does not have to wonder why the code was not run. The user gets a descriptive error message rather than a NullPointerException.

Since the error only occurs when the "play" window is closed. I Think (not actually looking at the "play" window close handler) that it could be captured there with an exception handler that would catch the null handle exception and kill it before it got high enough to be visible.
