When determining where to place a secondary window consider a number of factors, including the use of the window, the overall display dimensions, and the reason for the appearance of the window. In general, display a secondary window where it last appeared. If the user has not yet established a location for the window, place the window in a location that is convenient for the user to navigate to and that fully displays the window. If neither of these guidelines apply, horizontally center the secondary window within the primary window, just below the title bar, menu bar, and any docked toolbars.
