Hi, Adam,

I suggest, even if you have it working, that you examine mmalc's 
excellent "Bookmarks" example at <http://homepage.mac.com/mmalc/CocoaExamples/controllers.html
>.  It was amazingly helpful to me, in particular, with regard to 
setting up an array controller as a data source for drag-and-drop. :)

Cheers,
