Lightbox issues with Reviews

I’ve updated to the most recent version of woocommerce, my theme, and wordpress. I understand that lightbox (prettyphoto) is what makes the reviews palette appear. On my site, it is disturbing.

It first shows up for an instant, then disappears. I have deactivated it in my woocommerce settings, but it’s a shame because I would like to use the feature. Does anyone know of a way to correct this glitch?

Thanks,
Bob
