The problem seems to be at DashboardFrame.java at line 119:

// Set the size / look
        if (competition) {
            setPreferredSize(NETBOOK_SIZE); //1024x400 - this is your problem
            setUndecorated(true);
            setLocation(0, 0);
            setResizable(false);
        } else {
            setMinimumSize(MINIMUM_SIZE); //300x200

            // Closing operation is handled manually
            setDefaultCloseOperation(JFrame.DO_NOTHING_ON_CLOSE);

            DashboardPrefs prefs = DashboardPrefs.getInstance();
            setPreferredSize(new Dimension(prefs.width.getValue(), prefs.height.getValue())); //This is the dimension stored in the save file
            setLocation(prefs.x.getValue(), prefs.y.getValue());
        }

So the DashboardFrame will automatically be set to 1024x800 if you're in competition mode. The easiest (temporary) fix until the 2013 release would be to change

setPreferredSize(NETBOOK_SIZE);

to

setPreferredSize(new Dimension(width, height));

with (width, height) being based upon the size of your screen.
