Yes, I do mean the PCLOS Control Centre. Maybe I'm wrong about the system fonts, but something odd happened. After I removed Times New Roman, the next thing I did was try to run my browser (Chromium) but it just didn't appear. I reset the computer, and KDE didn't come up; I got the command line instead. If I log in as root and try to run KDE, I get a message that the X-Server won't run because it's unable to find font 'fixed' (which, you're right, doesn't sound like Times New Roman!). I installed Aptitude at the command line, and had a trawl through looking for fonts which might fit the bill as missing, but it's not the easiest program in the world to use, so I'm none the wiser (though I suspect my hair is slightly greyer...) Afraid I don't know enough about the command line, or how X works to figure it out.
