Re: Drag and drop in Carbon Emacs

[Steven Tamm]

I just checked this in.  The major visible change is that the green 
plus appears whilst dragging over a valid area, whereas before there 
wouldn't be a visible change.

However I couldn't actually drag onto an file dialog.  You can drag to 
a frame behind the dialog, but that is ignored.
