Hi Ian,

Here what I saw when going to the PGP site:

Windows XP Pro:
    IE 6.x:         No padlock
    Firefox 0.9.2:  Padlock on address bar and tab

Mac OS 10.2.8:
    IE 5.2:         No padlock
    Safari 1.0.2:   Padlock on address bar but no on tab
    Fixfox 0.8:     Padlock on address bar and tab
    Camino 0.7:     Padlock on address bar and tab

You stated that http://www.pgp.com is an SSL-protected page, but did you
mean https://www.pgp.com? On my Powerbook, with all the browsers I get an
error that the certificate is wrong and they end up at http://www.pgp.com.

I'm not sure if PGP deliberately set out to confuse na=EFve users since their
logo has been the padlock for a while. Many web sites have their logo
displayed on the address bar (and tab) when you go to there site, see
http://www.yahoo.com or http://www.google.com. Maybe Jon can answer the
question.

Respectfully,
Aram Perez
