/**
 * The following was coded to take care of little idiosyncracies
 * allowed and disallowed in cross window communication.
 * Specifically, Mozilla / Netscape allow a child window to
 * refresh their parent, regardless of whether or not the
 * parent is secure or insecure, with the child being secure.
 * In IE and Opera, this is considered a security exception.
 *
 * The correct behavior is? But who cares.  The method I came up
 * with to get around this is to create a listener that will
 * get called routinely (every .5 seconds), to see if a child
 * window has closed.  If it has, the parent will update itself.
 *
 * This specific functionality is obtained implictly by calling
 * openPopupRefreshUponClose(...).
