[RESOLVED] ComboBox.SelectedIndex can't go higher than 9?

[cicatrix]

What does this show?

Private Sub ComboBox1_SelectedIndexChanged(ByVal sender As Object, ByVal e As EventArgs) _  
                                   Handles ComboBox1.SelectedIndexChanged
     MessageBox.Show("item " & ComboBox1.SelectedIndex.ToString())
End Sub
