Internet Explorer throws an exception when you try to call the
onclick function by saved reference - perfectly correct
behavior. Opera seems to silently ignore the call. For Opera it
seems to be a common behavior to ignore bad calls without
throwing an exception (another example is calling document.write
by saved reference on a document that changed origin).
Finally, shameless plug. Our Browser Security Test
(http://bcheck.scanit.be/bcheck/) now checks for this vulnerability.
