you wouldnt believe it if i told you.. but put in a block to disallow

move or resize of an obj WHILE in the middle of a move or resize
already - some weird case someone has come up with where this happens
and things like smart clipped's "move relatvie by dx, dy" totally
screw up then. it's a totally unexpected case though. some circular
action has been created that logically shouldn't have existed.
