OK, cancel that. As so often happens when I finally give up and ask a question, the answer hit me the face a few minutes later. Still hurts, too: trouble was that in an earlier experiment I had overridden setFrame: in this derived class and had neglected to remove that - it was not configured to do anything yet... now we return to our regular programming.

Here's the essence: in responding to a mouse drag there is a place where I do this; NSPoint newLocation = event.locationInWindow; NSRect frame = self.frame; frame.origin = newLocation; [self setFrame: frame]; [self setNeedsDisplay: YES]; I can also do [self.superview setNeedsDisplay: YES]; However, nothing moves, and looking at this in the debugger I can see that self.frame is not altered by [self setFrame: frame]; Suppose the original frame is 100,100,200, 200 and the new location is 101,105 The new frame is thus 101,105,200,200 And yet if I then look at self.frame in the debugger by adding to the above frame = self.frame; I see it is still what it was before: 100,100,200,200. Apparently the call to setFrame had no effect. I am not using IB. This is all programmatic. Does anyone have a clue as to why that frame would not alter after setFrame: with a new value?
