Buy Buttons not showing up about a third of the time. WordPress/NextGen/Lightbox

Hi, my client's WordPress site is using the Nextgen Gallery Plus plugin with the Lightbox lightbox. About a third of the time, the Fotomoto Toolbar doesn't show up. Usually the first time you view a photo, the buttons are there. But if you close the lightbox, and view another image in the same album, they don't show up. His site is Thanks.
