Błąd przy tworzeniu DataGridView

Co jakiś czas pojawia mi się błąd: "This operation cannot be performed while an auto-filled column is being resized" podczas wykonywania metody form.Show(); Wygląda na to, że problem dotyczy DataGridView.
Spotkaliście się może z czymś takim?

Pozdrawiam,

Prześlij kod źródłowy.

Wywołanie:

 
foreach (Form form in MdiChildren)
            {
                if (form.Name == "SlownikiJednostki")
                {
                    form.Activate();
                    return;
                }
            }

            Slowniki.SlownikiJednostki child = new Slowniki.SlownikiJednostki();
            child.Name = "SlownikiJednostki";
            child.MdiParent = this;
            try
            {
                child.Show();
            }
            catch (InvalidOperationException)
            {
                child.Show();
            }

To podwoje wywołanie Show() to porada z http://dotnet.itags.org/web-forms/75052/ ale coś mnie nie przekonuje :-)

Główny problem jest taki, że błąd wyskakuje raz na kilka uruchomień.
Teraz zmieniałem tak, że w designerze dałem none zamiast fill natomiast:

 
this.Nazwa.AutoSizeMode = System.Windows.Forms.DataGridViewAutoSizeColumnMode.Fill;

wstawiłem do onLoad. Może to coś pomoże.
