Active page not selected and missing option

I’ve installed v1.2 on this site and set the selector to .art-menu. The tinynav is created and displayed, but the active page is not selected. In fact, no page is selected.

As a side note, it’d be great to make the “active” class a plugin option. My theme used a non-default one and I had to do some coding to adjust, instead of just entering an identifier in a field.
