Thanks David.  So basically you're saying that the links won't work on a mac
no matter what I do?  I find this odd as I have two sites; on one site all my
links work on the mac, but on the newer site I just created, none of the
external links work (internal links work ok).  In fact I created the new web
site by modifying the old one, so I can't understand why they stopped
working.  I'm using IE explorer on my mac.
