All is working well apart from one niggle: the user has to click and hold down the mouse button for about 1 second before a drag begins. This is most unintuitive and it took me a while to realise that this is what's required.

I haven't looked into that because I do want the delay; my app needs to tell the difference between mouseDown: that causes a drag and mouseDown: that should go to the collectionViewItem's contents instead.
But I do know that it's all done as a tracking loop in mouseDown: instead of mouseDragged: etc, so that's a place to start.
