on shutDown and close stack question

[Doug Lerner]

In my shutDown handler I want to make sure that all the stacks get closed,
because even though they do in OS X, they don't in Windows.

I have this in my shutDown handler:

  if "onlineStack" is among the lines of the openStacks then
    close stack "onlineStack"
  end if

But when I quit the app in Windows the onlineStack stack stays open and I
need to close it manually.

Any idea why?
