When I invoke with: $("a").boxy();
Bosy will load the href of that <a> into its popup container. The <head> section loads in a div within the popup. If I 'filter' with an option thus: $("a").boxy({filter:'body'}); the entire content is filtered out and the popup is empty. Beats me why Boxy even tries to display the <head> content in the first place. My head happens to contain a <link> to a css file (same one as the main page, merely so I can edit the popup layout. I COULD remove the <link> but that's both a hassle and unnecessary (or it should be).
