[Plugin: WordPress Multibox] Script not working

I can’t get this plugin to function for me. It seems that no matter what when I click on a link to an image (or I guess anything), it just displays said image in a blank window. Not what I want. Turned off Lightbox and NextGen, no change.

The page I’m talking about is here:

And the image link is in the upper left underneath the ‘next>’ link. Any help would be greatly appreciated. Thanks.
