Arrange layers dialog causes graph dimensions to blow up

[Antony Jan]

Either using Add Layer or the Arrange Layers dialog, I can successfully add a new layer of the correct dimensions (400x300 pixels) and relative position to an existing graph. However, the entire graph dimensions balloon to about 1384 x 16,777,215 pixels. While I can manually resize the graph, returning to the Arrange Layers dialog and pressing OK resets the graph dimensions to the absurdly large value. There has got to be a different way!!!!
