I tried to start the Hoth Campaign with Imperial Commander Windows and I couldn't scroll to view the whole map during setup, or go back to a previous instruction if I made a mistake / or Im not sure I did it correctly.
After an enemy group activates, you can always view its instructions by right clicking OR double-clicking the group's icon.
To view the map when there are other UI elements showing, such as a text box, deployment window, or other instructions, you can click the "eye" icon in the lower left of the app. This will hide all UI elements and allow you to freely move around the map. Click the "eye" icon again to resume the game.
