What about the following?

JacarandaShapes>>moveAllConnectedShapes
	| handle |
	handle := HandleMorph new
		forEachPointDo: [:point | | movementOffset |
			movementOffset := (self globalPointToLocal:
point) - (self position).
			self connectedShapes do: [:shape | 
				shape position: shape position +
movementOffset]].
	self currentHand attachMorph: handle.
	handle visible: false.
	handle startStepping.

The method above I use to move all the connected morphs in a Jacarandá
diagram at the same time. It uses a HandleMorph and #position: so they
aren't grabbed (picked) by the hand.

Anyway. I see that Ned had already answered you and probably his
solution is better than mine. :)

Hernán
