How to change the size of lightboxed slides

Hi everybody,

We are currently working on a project in which we require to use several lightboxed "Freeform Question" slides. By default, the lightbox is smaller than "normal" slides and it appears that Storyline doesn't allow to customize the size of these lightboxes.

Does anybody know how to change the size of the lightbox such that it has the same size as "normal" slides? I'm somewhat positive that it should be possible using javascript -- much like it is possible to use javascript to remove the "x" in the top-right corner that standardly appears whenever a lightbox is open.

Sadly, the typically suggested solution of using layers instead of lightboxed slides isn't an option, as we require to lightbox question slides.

Any help would be greatly appreciated!

Cheers,

Stephan
