3. Click anywhere in the System.Disk window to make it active.
If you click anywhere in an inactive window, it automatically becomes the active window. (Note that the Tutorial window is now behind the System.Disk window and no longer has the characteristics of an active window.)

4. Practice resizing and repositioning the two windows.
Experiment with different sizes and positions for the two windows. Try making them overlap in various ways, and then try making them both fully visible on the desktop. (If you don't remember how to resize or reposition a window, refer back to Session 2 of this tutorial.)
Note that each time you click in a window to make an adjustment, that window automatically becomes the active window.

5. Close the System.Disk window.

If necessary, click anywhere in the window to make it active. Then choose Close from the File menu. Only the Tutorial window remains on the desktop-which means it's automatically the active window.
