Changed body font to Georgia...or so I thought

This seems like a real simple problem, but its solution is not self-evident.

So I wanted to change the body font to Georgia. I went to MTO > CSS Files > content.css and changed the line to this:

font-family: "Georgia", "Times New Roman", serif;

It's still showing up as the default (Lucida Grande, I think). What am I missing? I've tried clearing cookies and cached files already; I've tried using Safari instead of Chrome. All: no dice.

Advice?
