Next button + Lightbox

Hi all

I have a Player trigger on a slide which is

"Jump to 1.2 Main Menu

    when user clicks Next button"

But it will simply not proceed to that slide when playing. Free Navigation is set. Can anyone suggest what it might be?? Same with Prev button, and is happening on other slides but not all slides.

Also when my Lightbox closes it leaves a weird second transparent Lightbox which also needs closing. This transparent Lightbox also apprears whenever I try to re-open the original lightbox (so i can't view a Lightbox twice.

What is going on?

Cheers

Morris.
