2D Text Menu, need some help.

[lxXTaCoXxl]

I've recently posted a code snippet of a working 2D text menu for Windows Forms Applications. However, as I was going through and revising this snippet (trying to make it better and add functionality to it) I've created two new problems. The first problem is that my text is not showing up on the form anymore (kind of the biggest problem), and the second is that my value is scrolling too fast on the key press events. I have a seperate class managing the events so that I can clean up source code in the main form .cs file. So here is my source code, hopefully you guys can help me figure out what I changed that made my text disappear. :/

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using System.Threading;

namespace Menu
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        Menu myMenu = new Menu(new Point(15, 15));

        MenuEntry Entry1 = new MenuEntry("Play", Color.Red);
        MenuEntry Entry2 = new MenuEntry("Options", Color.Red);
        MenuEntry Entry3 = new MenuEntry("Credits", Color.Red);
        MenuEntry Entry4 = new MenuEntry("Exit", Color.Red);

        private void Form1_Load(object sender, EventArgs e)
        {
            myMenu.AddEntry(Entry1);
            myMenu.AddEntry(Entry2);
            myMenu.AddEntry(Entry3);
            myMenu.AddEntry(Entry4);

            // UPDATE: Changed myMenu.SelectedIndex to myMenu.Length
            // Effect: Displayed the first label (not the others though).
            for (int i = 0; i < myMenu.SelectedIndex; i++)
                this.Controls.Add(myMenu.Items[i]);

            // Timer
            Updater.Start();
        }

        // Timer Tick
        private void UpdateMenu(object sender, EventArgs e)
        {
            myMenu.Update();
        }

        // Form1_KeyDown
        private void NavigateMenu(object sender, KeyEventArgs e)
        {
            myMenu.Navigate(e);
        }

        // Trying to complete navigation tests to get rid of INDEX OUT OF RANGE exception. This part was just part of that.
                    // Form1_KeyPress
        private void Navigate(object sender, KeyPressEventArgs e)
        {
            if (e.KeyChar == (char)Keys.Up)
                this.Text += "UP";

            else if (e.KeyChar == (char)Keys.Down)
                this.Text += "DOWN";

            e.Handled = true;

Found the problem:

//Line 146 (Change):
if (this.SelectedIndex == 0) // From
if (this.Length == 0) // To
