Can I view two pathways at the same time?

Yes, you can view two (or more) pathways at the same time.  Simply select: Cascade Document Windows or Tile Document Windows from the Windows menu above the Information Pane (in the Application Tool Bar).

If the Application Tool Bar is not displayed, select Program options by clicking on the tools button of the Home tab in the Information Pane. Then select 'No' for the option 'Auto-hide application menu bar' in the ‘Menu’ section of the ‘Program Options’ menu.

Alternatively, select the Alt key to view the Application Tool Bar.
