When I used previous version .NET Framework v2.0 Betta 2 it woked fine.
But today I intalled NET Framework v2.0.50727 and in MDI parent window ToolStrip from Child window don't merge!
Where the problem?

Example:

using System;

using System.Windows.Forms;

namespace Bug

{

public class MainWindow : Form

{

public MainWindow()

{

this.IsMdiContainer = true;

ToolStripButton tsb = new ToolStripButton("Parent");

ToolStrip ts = new ToolStrip();

ts.Items.Add(tsb);

ts.AllowMerge = true;

this.Controls.Add(ts);

Child ch = new Child();

ch.MdiParent = this;

ch.Show();

}

[STAThread]

public static void Main(string[] args)

{

Application.Run(new MainWindow());

}

}

public class Child : Form

{

public Child()

{

ToolStripButton tsb = new ToolStripButton("Child");

ToolStrip ts = new ToolStrip();

ts.Items.Add(tsb);

ts.AllowMerge = true;

ts.Visible = false;

this.Controls.Add(ts);

}

}

}
