Page hangs at "Select or enter gallery"

When trying to add an existing “NextGEN Gallery” to a page, I can click the “Add NextGEN Gallery” button and the window comes up that allows you to select the gallery to add.

Clicking “Select or enter gallery” within the Gallery tab, “Select or enter album” in the Album tab, or “Select or enter picture” in the picture tab all hang (the swirling circle comes up but nothing happens).

It used to work but I haven’t checked it in a while (so I’m not sure if it is 3.2 that broke it or an earlier update). I have the latest stable version of NextGEN gallery installed. This is a network site installation, not a single site. The site is running in lighttpd not apache.

I don’t see anything in the error logs related to this.

Anyone have any ideas about this? Your advice or suggestions would be much appreciated.
