Add Menu Item - app.response & Acrobat Help

I noticed that if I add a menu item (with a .js in the user folder) in the main Help menu, the first app.response will not let me enter any text. If I place that script in any other main Acrobat menu, it works. My guess it's because the Help menu already contain a search entry. That the only difference between this menu and the others. Am I riht with that finding? 

Try with this sample code:

function alertMe(){
var cMsg = app.response("Enter the message:");
var cMsg2 = app.response("Enter the message2:");
app.alert (cMsg+cMsg2);
}
//
app.addMenuItem({cName:"Alerte Me!", cParent:"Help", cExec:"alertMe();" });

 
Is their a workaround this?
