I prefer using the NSResponder methods because it doesn't foul up other event handling, and I thought that's what Apple people on this list have advocated (but my memory may be faulty). I recently discovered that NSSplitView's mouseDown: breaks mouseDragged: for subviews...which seems particularly odd since NSSplitView is useless without subviews. I wish there were a coherent story on this from Apple. If the frameworks force us to use while(1) loops, then just remove mouseUp:/mouseDragged: from NSResponder and be done with it.
