QuestionHelp - FormClosing event and FormClosed event fires to often Pin

Hi all,
I have an MDI window with a ButtonBar (defined as master) and from there I can call the child windows (outside the master).
And from one child window I am calling an DialogWindow.

And here comes the problem: Confused | :confused:
When I am closing this dialog window, the FormClosing event (of the dialog) fires 34 times, and after that the FormClosed event fires 10 times.
I am shure that the events are only initialized for one time.
So you can say that 3 layers are opened. (MDI-Master --> MDI-->Slave --> DialogForm)
It wouldn't be a problem at all, if the dialog window wouldn't hang up. The whole Program stops.

in the FormClosing method is only a quiet simple code.

Dialog_FormClosing(.....)
{
   try
   {
      Console.WriteLine("closing");
      if(!can_close)
      {
         Messagebox.Show("You have to finish your app first");
         e.Cancel = true;
      }
      else
      {
         e.Cancel = false;
      }
   }
   catch
   {
   }
}


The question is: Why fires the event so often ?
And why hangs up the dialog (the dialog does not close)

Some ideas ? - using .NET 2.0.xxx

Tnx
Frank
