This object is used to specify whether or not the personal bar is to be displayed in the newly opened window. The window.open() method is used to open the window, and the 'personalBar' is part of a comma delimited list of values which are placed within the opening and closing brackets of the open() method. Used as a statement in Netscape's Navigator, it is possible to change, using signed scripts, whether or not the personal bar is displayed as a function of user input. That is, the personal bar may be hidden after the window has been opened with the personal bar showing.
