NextGen Gallery Urgent help with multiple gallerys

Hi all,
I need urgent help to resolve an issue I’m having using multiple gallery’s on the same page that need to use image browser.
I have different gallery’s displaying there relevant thumbnails, that when clicked need to use image browser. All fine with one gallery but as soon as the page has multiple gallery’s when a thumb is clicked multiple instances of image browser also open, instead of the one instance of image browser that shows only the images from that gallery.

help please
