Glen;

Hey good info (in an offline email) it DOES make sense that I if 
register for X but if I drag Y then draggingEntered does NOT get 
called!!

THANKS for that whack on the head!

So I took your suggestion and registered for NSURLPboardType as well.
Now I get feedback!  Here's what the [[sender draggingPasteboard] 
types] is showing:

(which explains why i wasn't seeing a response for vCard drags!)

2007-04-27 15:46:14.693 XYZ[4945] pBoard: (
    "CorePasteboardFlavorType 0x6675726C",
    NSFilenamesPboardType,
    "Apple URL pasteboard type",
    "CorePasteboardFlavorType 0xC46C6E6B",
    "CorePasteboardFlavorType 0x73646C74",
    "CorePasteboardFlavorType 0x6F726769",
    "CorePasteboardFlavorType 0x626E6368",
    "CorePasteboardFlavorType 0xC4706431",
    "CorePasteboardFlavorType 0xC4697475"
)

This listing makes me think I have some machine configuration hosed 
up somewhere.
This not what I am used to seeing for pBoard types.
Google on 'CorePasteboard' doesn't seem to head anywhere useful.

Anybody got any ideas?
Steve
