Procedura per riprodurre il problema.

1. Avviare una nuova applicazione Windows in progetti C# .
2. Aprire il codice di Form1.cs e quindi sostituire il contenuto esistente con codice di esempio seguente:

   namespace MDIMenu
   {
   	using System;
   	using System.ComponentModel;
   	using System.Drawing;
   	using System.Windows.Forms;
   
   	public class MainForm : System.Windows.Forms.Form 
   	{
   		/// <summary>
   		///    Required designer variable.
   		/// </summary>
   		private System.ComponentModel.Container components;
   		private System.Windows.Forms.MainMenu mainMenu;
   
   		public MainForm() 
   		{
   			// 
   			// Required for Windows Form Designer support
   			// 
   			InitializeComponent();
   
   			//Setup MDI stuff
   			this.IsMdiContainer = true;
   
   			//Add Window Menu
   			MenuItem miWindow = mainMenu.MenuItems.Add("&Window");
   			miWindow.MenuItems.Add("&Cascade");
   			miWindow.MenuItems.Add("Tile &Horizontal");
   			miWindow.MenuItems.Add("Tile &Vertical");
   			miWindow.MdiList = true ;
   			// Adds the MDI Window List to the bottom of the menu.
   
   			//Add Help Menu
   			MenuItem miHelp = mainMenu.MenuItems.Add("&Help");
   			miHelp.MergeType = MenuMerge.MergeItems;
   			miHelp.MergeOrder=0;
   			miHelp.MenuItems.Add("&About");
   
   			Document doc = new Document();
   			doc.MdiParent = this;
   			doc.Show();
   		}
   
   		/// <summary>
   		///    Clean up any resources being used.
   		/// </summary>
   		protected override void Dispose(bool disposing)
   		{
   			if (disposing) 
   			{
   				if (components != null) 
   				{
   					components.Dispose();
   				}
   			}
   			base.Dispose(disposing);
   		}
   
   
   		/// <summary>
   		///    Required method for Designer support - do not modify
   		///    the contents of this method with the code editor.
   		/// </summary>
   		protected void InitializeComponent()
   		{
   			this.components = new System.ComponentModel.Container ();
   			this.mainMenu = new System.Windows.Forms.MainMenu ();
   			this.Text = "MDI Menu Bug";
   			this.AutoScaleBaseSize = new System.Drawing.Size (5, 13);
   			this.Menu = this.mainMenu;
   			this.ClientSize = new System.Drawing.Size (450, 200);
   		}
   
   		/// <summary>
   		/// The main entry point for the application.
   		/// </summary>
   		[STAThread]
   		public static void Main(string[] args) 
   		{
   			Application.Run(new MainForm());
   		}
   
   	}
   }
   					

3. Aggiungere un Nuovo Windows Form nel progetto. Nel nuovo modulo, sostituire il codice esistente con il seguente codice di esempio:

   namespace MDIMenu 
   {
   	using System;
   	using System.ComponentModel;
   	using System.Drawing;
   	using System.Drawing.Text;
   	using System.Windows.Forms;
   
   	public class Document : System.Windows.Forms.Form 
   	{
   		/// <summary>
   		///    Required designer variable.
   		/// </summary>
   		private System.ComponentModel.Container components;
   		private System.Windows.Forms.MainMenu mainMenu;
   
   		public Document() : base() 
   		{
   			// 
   			// Required for Windows Form Designer support.
   			// 
   			InitializeComponent();
   
   
   			//Add File Menu
   			MenuItem miHelp = mainMenu.MenuItems.Add("&Help");
   			miHelp.MergeType = MenuMerge.MergeItems;
   			miHelp.MergeOrder=0;
   			miHelp.MenuItems.Add("This Child Menu 
                                             should not appear when clicked on Window menu");
   		}
   
   		/// <summary>
   		///    Clean up any resources being used.
   		/// </summary>
   		protected override void Dispose(bool disposing)
   		{
   			if (disposing) 
   			{
   				if (components != null) 
   				{
   					components.Dispose();
   				}
   			}
   			base.Dispose(disposing);
   		}
   
   		/// <summary>
   		///    Required method for Designer support - do not modify
   		///    the contents of this method with the code editor.
   		/// </summary>
   		private void InitializeComponent()
   		{
   			this.components = new System.ComponentModel.Container();
   			this.mainMenu = new System.Windows.Forms.MainMenu();
   			this.AutoScaleBaseSize = new System.Drawing.Size(5, 13);
   			this.Text = "Child Window";
   			this.ClientSize = new System.Drawing.Size(392, 117);
   			this.Menu = mainMenu;
   			this.WindowState = FormWindowState.Maximized;
   		}
   	}
   }
   					

4. Eseguire l'applicazione e quindi fare clic su menu finestra . Viene visualizzato il menu Guida .
