Bug 25419 [Dialogs] Can't Maximize Window: "Preferences"
Build: 200210181211 The "Preferences" window cannot be maximized since it neither has a maximize title bar button nor does the title bar respond to being double-clicked. The only work around is to reside the window manually by dragging the border. For short-lived windows this is too detail-oriented and time-consuming.

* </p>
 * <p>
 * Note that for backward compatibility, a message of type <code>ERROR</code> 
 * is different than an error message (set using <code>setErrorMessage</code>). 
 * An error message overrides the current message until the error message is 
 * cleared. This method replaces the current message and does not affect the 
 * error message.
 * </p>
 *
 * @param newMessage the message, or <code>null</code> to clear
 *   the message
 * @param newType the message type
 * @since 2.0
