Click on the Window menu. Notice the number of windows available at the bottom of the menu. A check mark is displayed on the menu line for the window that is currently active. It is possible to instantly switch to any of the other windows listed at the bottom of this menu by clicking on its menu line, but instead, we want to create a completely new window: Click on 'New', then click OK in the New Window dialog box to accept the default (Gantt) window type. Although the new window now presented probably looks much like the previous window, you really are looking at a new, different window now. Click on the Window menu to see the new window listed at the bottom of the menu, named 'Gantt'. Click the Window menu again to close it without selecting anything.
