RefreshPropertiesAttribute does not refresh PropertyGrid

Is there a known problem with the RefreshPropertiesAttribute not being able to force PropertyGrid to refresh?

I have a simple form that contains a PropertyGrid. I create an object, and give it to PropertyGrid.SelectedObject. I see the properties of that object displayed.

I then click a test button that causes the value of one of the object's properties to change. However, the PropertyGrid does not refresh to display the new value. Only when I click on the grid cell for that property does it refresh.

I decorated the property with the RefreshPropertiesAttribute as follows, but it has no effect.

public class Foo
{
  private bool m_Flag;

  [RefreshProperties( RefreshProperties.All )]
  public bool Flag
  {
    get { return m_Flag; }
    set { m_Flag = value; }
  }
}

I created my own CustomPropertyGrid class that derives from PropertyGrid and overrode Refresh(). Thus, I am certain that Refresh() is not being called.

public class CustomPropertyGrid : System.Windows.Forms.PropertyGrid
{
  public override void Refresh( )
  {
    base.Refresh();
    Debug.WriteLine( "*** Refresh ***" );
  }
}

My development environment is:
- Visual Studio 2008
- Target Framework = .NET 2.0

Any suggestions are appreciated.
