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
I have a custom view that contains a (covering) NSImageView. The latter
is disabled. I want the custom view to handle all drag operations. This
works fine as long as I don't drag in a type (e.g., NSFilenamesPboardType)
that NSImageView directly supports. setAllowsCutCopyPaste:NO for the
NSI
