[Mono-winforms-list] NumericUpDown event problem

I have a very simple Winform - it consists on a single NumericUpDown
button with the ValueChanged event set onto the buttons.

I'm currently seeing though that the event is being triggered twice. Can
someone confirm this behaviour so I can enter it into bugzilla?

using System;
using System.Drawing;
using System.Windows.Forms

class simpletest : Form
  private NumericUpDown number;

  public simpletest()
     number = new NumericUpDown();
     number.Location = new Point(12, 12);
     number.Name = "numberbox";
     number.Size = new Size(50, 23);
     number.ValueChanged += new EventHandler(number_ValueChanged);

     AutoScaleBaseSize = new Size(5, 13);
     ClientSize = new Size (80, 40);
     Name = "simpletest"
     Text = "NumericUpDown text";

  private void number_ValueChanged(object sender, System.EventArgs e)
    Console.WriteLine("Event triggered happily");

  public static void Main()
    simpletest t = new simpletest();

You should find that when compiled, the event is called twice instead of
once. I've only tested this under Mono (compiled from source at 16:00hrs
GMT), so don't know what will happen under .NET
