[Plugin: NextGen] Thickbox function not working

I have NextGen installed on a WordPress site, and the Thickbox funtion will not work. Instead it is just opening up the image. Some of the other effects are working, but NOT Thickbox, and of course thats what my client is damanding. I tried upgrading, and uninstalling/reinstalling and it doesn’t seem to be helping at all. Any thoughts?
