I would start by overriding -saveDocument: and -saveDocumentAs: in your NSDocument subclass with a breakpoint so I can see what is being done. I might also start by subclassing -runModalSavePanelForSaveOperation:delegate:didSaveSelector:contextInfo: to see if that is the method used in these cases. Then there are also autosave issues if you intend to support autosave in your app...
