[JS CS3] Why do sub menus disappear?

Question

Hello,
The below script creates a new menu with three sub menus. One of the sub menus invokes a script, while the other two are still under construction. This seems to work except for one irksome thing: When I close InDesign and then reopen it, the menu ("PPcheck") exists but the sub-menus are no longer under the menu. How do I make them permanent?
Thanks,
Tom
#targetengine session
var englishCheck = new File( "~/Library/Preferences/Adobe InDesign/Version 5.0/Scripts/Scripts Panel/Format/formatCheckWindow.jsx");
var englishCheckMenu = app.scriptMenuActions.add("Main-English");
englishCheckMenu.eventListeners.add("onInvoke", englishCheck, false);
var frenchCheckMenu = app.scriptMenuActions.add("Main-French");
frenchCheckMenu.eventListeners.add("onInvoke", underConstruct, false);
var spanishCheckMenu = app.scriptMenuActions.add("Main-Spanish");
spanishCheckMenu.eventListeners.add("onInvoke", underConstruct, false);
//following creates menu if it does not exist
try{
    var scriptMenu = app.menus.item("$ID/Main").submenus.item("PPcheck");
    scriptMenu.title;
catch (e){
    var scriptMenu = app.menus.item("$ID/Main").submenus.add("PPcheck");
//following adds sub menu items
scriptMenu.menuItems.add(englishCheckMenu);
scriptMenu.menuItems.add(frenchCheckMenu);
scriptMenu.menuItems.add(spanishCheckMenu);
//****functions******
function underConstruct(){
    alert("The French and Spanish semi-automatic checkers are still under construction.");

Hi Tom,
I'm not sure wheather it will work, but try two things:
1. put quotes on session so it states
#targetengine "session"
2. don't put "false" in eventListeners
it's just a guess, but maybe it works
