Thanks, Marek So how would I go at this? Since I want to store that data into the document, I’d need, in dataOfType:error:, to create a NSKeyedArchiver, and then would I just encode self.windowControllers? Then, in readFromData:ofType:error:, I would read in the coder, and in makeWindowControllers I would then re-create the window controllers? Would that work? (I have started to try exactly that, but I have not yet succeeded with making it work. It somehow seems a bold thing to do.)
