Hi everybody,
 
I just started playing with System.Windows.Forms on Windows.....and I got the error when  I set Button's Text property. It works with .net 1.1
 
This is my code..
 
using System.Windows.Forms;
using System;
public class Form1:Form
{
    Button b;
    public Form1()
    {
        b = new Button();
        b.Text = "Accept";
        b.Click += new EventHandler(b_Click);
        this.Controls.Add(b);
    }
    private void b_Click(object sender,EventArgs e)
    {
        System.Console.WriteLine("clicked");    
    }  
    static void Main()
    {
          Application.Run(new Form1());
    }
} 

with mono 1.0.4 I got 

C:\usuarios\Development\mono>mono window2.exe
Unhandled Exception: System.ArgumentException: Invalid Parameter. A null referen
ce or invalid value was found.

with mono 1.1.2
