/** Function: invokePopup
 *
 *	- Popups are appropriate for small amounts of ancillary information...
 *	- Always display popups smaller than the parent window, so that the user knows it's a different window.
 *	- The address bar, status bar, standard buttons, and resize handle should be visible and functional
 *	  (unless there is a compelling reason to deviate.)
 *	- There should always be a "Close Window" link in the bottom center.
