Replace component - Manipulate Models

I am trying to replace a component in an assembly in Creo 2. I have selected "Unrelated Component" and when I select "Edit Ref Table", the window, which has the part I am replacing and the new part, is displaying the components nearly on top of one another.  The problem is that several of the surfaces I need to relate to one another are not easily visible as the other component is blocking the view.  Does anyone know if there is a way to manipulate one of the components within this window so that I can view them side by side?
