Hmmmmmmmm ... I see that Lyne realized,

Huh, it's NOT my firewalls!!

I have noticed that text size is handled differently by Netscape and Internet Exploiter. 

In addition, the renderosity web pages do NOT set text size in a consistent way. 

e.g. In this message thread, viewed in Netscape the messages all have consistent
text sizes ... OTOH, viewed in IE (which I must do because the FCK editor still
doesn't work in Netscape), the text size varies ... a lot!
