Had a bit of difficulty finding where this code resides, so I'm blogging it. The actual location of mallarme.uvic.ca is /lang02/www/fall07/coupde/penultima2/web_pages.

At ER's request, I've made the popup div position: fixed. I also noticed that clickable elements didn't have a pointer cursor, so I've fixed that. Just two minor fixes in style.css.
