Is this the expected behaviour? I'd expect that returning NO would
prevent the user from selecting that item in any way. Which it
does for folders at least.
The SAVE panel always greys out all filenames, since you're not
choosing a file, but saving one. As a convenience, it copies the
name of anything you click - occasionally this is handy but it is
somewhat odd (but clearly intentional) behaviour really. So I
suspect that the delegate method is not contributing to the filename
situation, only to stop you going into subfolders.
