I'm trying to implement drag & drop in my NSCollectionView,

delegate is indeed connected.
Not to discourage you, but my experience with NSCollectionView in
10.5 was that it was extremely buggy; in the end it probably cost me
more time to try to get it working in my app, than it would have to
just write my own equivalent. But hopefully this is better in 10.6,
so don't give up yet :)
What helped me out was to look for Apple sample code using
NSCollectionView, and change it around to try to add the feature I
was trying to make work. Sometimes that showed how a seemingly-
innocent difference in my code or nib was actually preventing it
from working, for some reason.
The only sample code seems to be IconCollection, and it doesn't do
drag & drop.
