[Plugin: NextGEN Gallery] How to show description?

I’m using the “gallery floating caption” of the Highslide-function (http://www.kennethjansson.net/highslide4/examples/gallery-floating-caption.html) to show pictures in my gallery. The thing is that in album-mode I can display the description text but as an widget Nextgen don’t want to display any description, why is this? And how do I fix it? I have search the Internet for answer but their is none to find.
