Hi Denis,

Can you send us a sample application that reproduces this behavior to support@xceed.com so that we can investigate further?

DockingWindows exception occured when Close the window.

I've investigated your ImagingCS example for docking windows.

I've added following source code to

ColorPalette.cs

protected override void OnClosed(EventArgs e)
{
Imaging._Imaging.CloseToolWindow(this);
base.OnClosed(e);
}

and replace ColorPalette_VisibleChanged

private void ColorPalette_VisibleChanged(object sender, System.EventArgs e)
{

}

and following code to Imaging.cs

/// <summary>
/// The main entry point for the application.
/// </summary>
[STAThread]
static void Main()
{
_Imaging = new Imaging();
Application.Run(_Imaging);
}

public static Imaging _Imaging;

public void CloseToolWindow(ToolWindow tw)
{
m_manager.ToolWindows.Remove(tw);
tw.Dispose();
}

When Toolwindow X button pressed I've got the following crash application exception:

{"Collection was modified; enumeration operation may not execute."}
