I just noticed another issue: When you click to view the large image, the menu stays on top of the image rather than dimming and going behind. (Example: Click to enlarge)

In in stylesheet_lightbox.css, change the z-index of #overlay to 9000 as reccomended here but to no avail.

This cart is a Zen 1.3.6 and I am using the Zen Lightbox mod.

Thanks for whatever assistance anyone can give!
