Well, it's a very simple form

using System;
using System.Collections.Generic;
using System.Text;
using System.ComponentModel;
using System.Windows.Forms;
using System.Drawing;

namespace EGCL2
{

    // Forma base
    public class WinFormaBase:Form
    {
    
        public  WinFormaBase()
        {
            this.Width = 511;
            this.Height = 371;
            this.Text = "WinFormaBase";

            // Añado un boton
          
            
           // egButton btnSalir = new egButton();
           // btnSalir.Left = 414;
           // btnSalir.Top  = 297;
 
           // this.Controls.Add(btnSalir);
          

        }

        private void InitializeComponent()
        {
            this.SuspendLayout();
            // 
            // WinFormaBase
            // 
            this.ClientSize = new System.Drawing.Size(503, 337);
            this.Name = "WinFormaBase";
            this.Load += new System.EventHandler(this.WinFormaBase_Load);
            this.ResumeLayout(false);

        }

        private void WinFormaBase_Load(object sender, EventArgs e)
        {

        }

    }
    // fin winformabase

}

>Hi there, can you post your form class code here, I had something similar a year or so back but can't remember how I fixed it, seeing your code might jog my memory
