 * adapted by Wolfgang Ritzinger <aargon@rat.at>
 * 2002-08-20: the position given in the array of each menue is now
 *   set relative to the beginning of the menue. so the offset-array
 *   is not used any more
 *
 * Wolfgang Ritzinger <aargon@rat.at>
 * 2002-10-24: call the functions popup() and closemenu() only if they
 *   are defined. this avoids the javascript error when the document
 *   is purged, and thereby destroys the functions.
