 * updates:
 * 04.19.04 fixed cascade problem with menus nested greater than two levels.
 * 12.23.03 added hideCurrent for menu actuators with no menus.
 * 04.18.03 fixed render bug in IE 5.0 Mac by removing that browser from compatibility table ;)
 *	    also made gecko check a little more strict by specifying build no.
 * 02.20.05 positioning of the dropdown-menu adapted to my sites (boehnert.com)
 * 14.09.05 bug fix for select-tag and others
 * 09.03.06 2 versions of the funcion toString() to avoid error messages in mozilla (MB)
