[Plugin: NextGEN Gallery] Singlepic return to top of page ?

When displaying an image with [ singlepic id=x ], the option is available to click on the image to view a larger version. When clicking again, on the larger image, you return to the blog post or page. With the ‘Default’ theme, the return occurred to where the singlepic image is located, so returning to the location from where the image enlargement was called from. With my new theme (Suffusion) the return from the large image is to the top of the post, forcing a reader to scroll down again.

Anyone knows why this happens and how this could be solved ?
