Why is my title in smallcaps now?

WordPress is doing something weird now. Yesterday the head of the site was not in all caps, and today it is.

Hmm.

Ok, I figured it out. I guess I must have installed some new font on this computer – “Trajan Pro” – and the header was showing in that font. I deleted it from the stylesheet and now it defaults to Lucida Sans Unicode, which is what I wanted.
