OK. I found a bug that is not logged as a defect. To duplicate the problem, open the DxDesigner Link in PADS Layout. Select a pin in DxD. Then select a component in Layout. RMB. Move and Rotate will both be grayed out, and CTRL+E and CTRL+R don't work either. You need to exit Layout and come back in to reset these options. I hope it gets fixed eventually. This one makes it tough to place decoupling caps on components that have multiple power pins tied to the same net. The guys at Mentor were great in helping me find the steps that cause the problem.
