Re: dumb bindings/user defaults question

Hmmm.  I knew Aaron Hillegass's book has you do it in a separate nib, unfortunately, both my copies are in storage from my recent move, so I followed the directions in Apple's "Binding Your Preferences in Cocoa" tutorial instead, which suggests putting the preferences panel in MainMenu.nib of a document based app.  That does make sense that it is timing though. 

I will give this a try later, when I have my mac in front of me.  Would it be better if I added a panel to my myDocument.nib?

Thanks.
