Subject: Athena onbeforeunload ?
To: Twisted Web World <twisted-web@twistedmatrix.com>

Hi all,
Trying to have the server know at once when a client goes away.
Seemed like function bindEvents of Nevow.Athena.PageWidget would do the trick, but...
Checking with alert's in bindEvents()  (ok), and function onbeforeunload; however, the latter doesn't seem to get called??
Please, what am I missing here?
