Problems with popup box and purchase button

Hello,

Very nice plug-in, sinds there are not many plug-ins that have the same functions. But i have encountered some problems.

I made a ‘test’ page with two photo’s. http://mauriceverschuur.nl/database/

The first problem is when i click on ‘Purchase’. As you can see the text doesn’t fit in the lightbox/popup.
Second. When i click on a photo, i cant click on the ‘purchase’ button that appears.

What can i do to solve these two issues?

Kind regards.
