C# bug

Here is some code.

If you make a form using it and run it, it should produce three labels.

It does on my PC. It doesn't on any of eight other PCs I have access to.

Why not?

namespace TestStat
{
    partial class Form1
    {
        ///

        /// Required designer variable.
        ///
        private System.ComponentModel.IContainer components = null;

        ///

        /// Clean up any resources being used.
        ///
        /// true if managed resources should be disposed; otherwise, false.
        protected override void Dispose(bool disposing)
        {
            if (disposing && (components != null))
            {
                components.Dispose();
            }
            base.Dispose(disposing);
        }

        #region Windows Form Designer generated code

        /// the contents of this method with the code editor.
