Hi Lee Ann,
Thanks for the info.. I was going to ask you if you had done any more digging.
Heheh, my users are mostly using Lion, too.
I guess more bug reports with Apple is the way to go on this.

As others have pointed out, the selection takes about 1 second for a drag operation to be processed. This is a real sore spot when using the NSCollectionView in my app. My beta testers are actually logging this as a bug.

It is better in Lion and the users who filed bugs against my app in Snow Leopard seem happy with Lion.
