My copy of IE3.02 for Win95 seemed to treat whatever value (even as 
"ex", as in "3ex") as pixels too.  IE4pr2 seems to handle it 
correctly, though.

At this point I test pages on the browsers to see that they are 
legible and reasonably-good-looking on both major ones. My only
complaint now is that IE4 has been messing up borders. Or maybe NN 4 
handles them imporppoerly? ...

If I do the following:

  #bordered {
    border-top-width: thin;
    border-bottom-width: thin;
    border-style: double;

Netscape Navigator will only show top and bottom borders and render 
them as double lines.  MSIE 3 doesn't show them (which is tolerable) 
and MSIE 4pp2 renders borders on all four sides, and renders 
mangled-looking lines to boot.
