To "Cascade" Open View Windows
Do one of the following:
Each open view window is assigned an equal amount of screen space, but only the lowest numbered view window is entirely visible. The other open view windows are stacked beneath this view window with only their title bars visible.
Tip: To bring a cascaded view window to the front of the stack, click its title bar. When the title bar is not visible, place the pointer over one of the windows' borders, so that a resizing double-arrow appears, and click.
