Problems with courier font

[Derek Meister]

I'm currently running a Hoary Hedgehog box upgraded a few weeks ago from
Warty, so I'm not sure if it's merely a post-update problem that I'm
having.

Whenever I go to a website that uses the "courier" font (not "courier
new"), the font isn't rendered at all. No other font seems to have this
problem, and the problem seems to occur across programs.

Here's an HTML example I created viewed through Firefox:

The lines are not normally rendered highlighted, that only occurs when I
highlight them normally, as I did when taking the screenshot to show
that the text is there, just not with the font being rendered.

I installed Konqueror and Mozilla just to make sure it wasn't a Firefox
issue, but the problem exists there as well.

I brought up Nautilis and the fonts:/// directory to see if I have the
Courier font:

Should that file be different than the others shown?

If I bring up the Font Preferences, and then try to select Courier from
the list, it's not rendered there either, unlike all the other fonts:

Suggestions?
