Params title is the name of a window that is open.
Action Closes the window if it is open.
If the window is not open, this verb has no effect. Returns True if the window is open and can be closed, false if the window is not open. This time, the verb returns false because the window is already closed. This verb cannot be used to close the Main Window, since that would cause the database to be closed and the script to be terminated. If this is desired, use fileMenu.close instead of window.close.
