I am worried about the performance implications of this. Should I not be? Implementation will tell, of course. I have gone back and forth between the modal approach and the “three-method” approach a couple times. I am now using the modal approach because it resulted in much smoother dragging and resizing. But I have recently upgraded to a new iMac Retina, with much faster processor; I’ll shift back to the three methods when I put in the fix.
