Kill a Standalone

[Bridger Maxwell]

Hey,
  I am sure this is a common question, but I can't find any posts that
address it.  I compiled a standalone application, but I created my own
titlebar and my own exit button.  The exit button has the script "delete the
current stack".  This works to hide the stack, but the process never
dissapears (I am using Windows).  I even have the destroystack property set
to true.  What is the command to completely close a standalone application?

  TTFN
