Doc on Controller Content vs. Parameters in Interface Builder Bindings panel ?

Hi all, I've googled around quite a bit but can't seem to find a full reference on all the settings of the Bindings panel in Interface Builder. In particular, in the case of a controller object (NSArrayController) and a Core Data model, I'm not sure what the distinction is between the "Co

Hi, So yes, as people mentioned you shouldn't move an application while it is running, so the solution is obviously to move it when it is not running. You will need a little tool that you launch with NSTask that does the move for you. As you noted, Sparkle does everything you want, except
