[Interest] Triggering Actions on Application Close

[andy fillebrown]

I think the problem might be the use of the "Force quit" button.  That is
not a normal way to close an application.  Pressing the "Force quit" button
is similar to using the OS to kill the process. I'd be surprised if any
slots were called in that case.  Try closing the application like a normal
user would.

Cheers,
