Lightbox by Pixelgeek and select option issue

Hi guys who use custom coded lightbox by Pixelgeek. Lightbox is working fine, but there is only one problem that I can’t solve. If an any cms-driven option is selected on the same page with lightbox, the thumbnail ceases to be clickable. If you reload the page and the option selector is reset, the lightbox will work fine again. This makes this lightbox unsuitable, for example, for an e-commerce product page. Maybe it’s already been solved?
