//// code for pop-up menus

// how it works:
//  When the mouse passes over one of the main navigation buttons, it calls
//   show_menu_exclusive() to swap the button image, open that button's pop-up menu,
//   and close any others that might be open.
//  When the mouse leaves the nav button, it starts a delayed restore of the button image
//   and closing of that pop-up menu by calling start_delayed_hide_menu(). The closing
//   is delayed because the mouse might be entering the pop-up menu. If not, then the menu
//   will either be closed by the delayed call to do_delayed_hide_menu(), or by entering
//   a different navigation button.
//  When the mouse enters a pop-up menu button, it cancels the delayed close of that
//   pop-up menu with cancel_delayed_hide_menu().
//  When the mouse leaves a pop-up menu button, it starts the delayed close.
//
//  In addition, the current section's menu is opened when no other menu is active.
//

//// globals

// variable records which menu is currently open
var open_menu = "";

// timer for delayed hide
var timerid = null;

//// functions

//

    timerid = null;
  }

  if (open_menu == menuname)  // return if this menu already open
    return;

  if (open_menu != "") {      // restore main navigation button
    // find image object
    var oldnavobj = MM_findObj(open_menu);
    if (oldnavobj != null) {
      // get image src

      var i = src.lastIndexOf("_on.gif");
      if (i >= 0) {
        src = src.substring(0,i)+"_off.gif";
      }
      // swap back unhighlighted image
      oldnavobj.src = src;
