You could observe for window sheet notifications and invalidate menu
items when your sheet is displayed (by implementing the
validateMenuItem: method in your controllers).
I've not used it myself, but you might be able to invalidate controls
in your documents other views by implementing
validateUserInterfaceItem: in your document controller. You might have
to write a category on the controls you use in order for this to work.
