thumbnails flash on page load, but nothing displays

i made the slidesow via the page editor interface. the slides show up in the slidesow section, but nothing displays when i load the page view.

also, will this new generation of portfolio slideshow display legacy slideshows? my guess is yes sincethe documentatin references inserting slideshows from other pages, but since i can’t get the new version to work at all i cannot test that guess.
