Re: NSImageView blocking drag -- solved

That post was in the middle of the night when I couldn't sleep.  I
researched the archives this  morning and found the solution.  I added an
outlet in my controller to the NSImageView and in awakeFromNib called
unregisterDraggedTypes for the NSImageView.  Problem solved.  However, I
still think that this should be the default behavior for a disabled view.
