Great plugin - really like it! However, I'm having a problem with it on WordPress Multisite.
It works fine in the main site, however it doesn't work properly on subsites. The problem is that the options window for a window won't drop down. I made a short video demonstrating the problem - in the video you'll see that the menu's don't open on the subsite (seemingly because there is no content to open - see video to understand what I mean). They do open, though, for the main site.
Here is the video: http://screencast.com/t/ZGQ3MWI2NT
