I have just upgraded to InDesign CS4 and cannot see where in the Preferences or elsewhere I can alter this behaviour. Previously when a window was resized its content stayed where it was. Now it moves relative to the window but without resizing. For example I am looking at an InDesign window almost as big as my monitor; when I make the window narrower by moving its right-hand edge to the left, the displayed content moves left to remain centred in the window, but at the same percentage display. How can I reset it so that the content does not move?
