Ah... Have you read the documentation for NSCell's -hitTestForEvent:inRect:ofView: ?
In particular the note: If the cell not disabled, and it would track, return NSCellHitContentArea |NSCellHitTrackableArea. I believe that for dragging to work you do NOT want to return NSCellHitTrackableArea. What happens in your custom cell class if you return just NSCellHitContentArea? (I'm assuming from your original message that you had been using the default hit test implementation.)
