NextGEN Pro Horizontal Filmstrip – question

Hello,

Is there any way to launch the lightbox when clicking on the main picture displayed in a Pro Horizontal Filmstrip, or no ?

Currently, it behaves so

– if I display the play controls, it starts/stops the slideshow (totally what is intended) when clicked
– if I don’t, it … behaves strangely when clicked. The whole “object” (i.e. the picture+the filmstrip below) “pop” outside of the current container (e.g. an article) and displays itself top left, over the rest of the page. Not exactly what one would intend.

Maybe a conflict with the theme, a simple child of Twenty Thirteen….

any idea ?

Thanks
