Thumbnails load properly, but the images pop open in a new window. I've tried a few of the suggestions in the forums, but am not having luck getting this to work properly on my site. I have the following install:

• Joomla 1.0.13
• Rockettheme template Versatility III
• FW Tool Tips
• JCE Editor/JCE Utlities
• Rok Slideshow

I tried the hints here, although the latest version of JCEUtilities uses JQuery by default.

This is the url for my site:
beta.pixelante.com/index.php?option=com_content&task=view&id=54&Itemid=47

This hack did the trick:

Rockettheme templates load both mootools and slimbox files, so it isn't needed. I would be nice if omitting these was an option on the SIG plugin configuration.
