It sometimes happens that the link between the north arrow and linked viewport gets broken, which results in all the north arrows pointing to the top of the screen and not to the viewport north. To rotate the north arrows manually or to link them to a viewport can be time-consuming. If you want to rotate all the north arrows simultaneously, use the Devotech iDAS Rotate North Arrow command.
