On the demo I fixed to accommodate Netscape's 'missing </P>' bug
the relative sizes change when I change the browser's default size.

You have used a SPAN for the 1em text inside your classed P element.
Therefore, since em refers to the parent element, the 1em text will be
the same size as the parent paragraph: 10pt. What is happening here is
correct, except in the case of Verdana on NSN, where the 1em Verdana is
larger than the 10pt.
