In "Billy's" defense, this is expected in most
JavaScript-enabled browsers.

Here's a Firefox version:

<a href="http://microsoft.com"
onClick="window.setTimeout('document.write(unescape(\'%3cscript%3ewindow.location=%27http://google.com%27%3c/script%3e\'))')">Microsoft</a>

IFF that is the case, then it is an extraordinarily
brain-dead design, 
as it breaks the very critical "rule" that you should
NOT surprise the 
user.  A URL link that is shown in the interface to go
one place, but 
which goes somewhere else is fundamentally broken
under that rule.

If this is by design, then it's another case of a
feature that breaks 
Billy's admonition that security is to trump features,
so should be 
fixed.
