Why does it seem that ONUNLOAD doesn't fire with NN when the window is closed??

Martin Honnen, Jap Boon Churn,
People use
<BODY ONUNLOAD="alert('unload')">
to check whether the unload event fires/the onunload handler works.
That way it seems with NN that the event doesn't fire when you close
the window as the alert doesn't appear. It is however the case that the
alert dialog is swallowed by the closing window ALTHOUGH the unload
event fires. For instance try
<BODY ONUNLOAD="java.lang.System.out.println(event.type)">
and then close the window and check the java console and you will find
the output of the onunload handler.
So don't expect alert/confirm/prompt dialogs to show up when called from
<BODY ONUNLOAD
with NN but otherwise your onunload handler will probably work
reliably.
