[Mono-osx] winforms in mono 1.1.8.1 on OSX 10.4.1

[MrcLrssn at netscape.net]

Hi!

I'm trying to use winforms in mono 1.1.8.1 on OS X 10.4.1.

The following class:

using System;
using System.Windows.Forms;

public class MyForm : Form {

        public MyForm() {
              this.Text = "Hello Form";
        }

        public static void Main() {
                Application.Run(new MyForm());
        }
}

compiled with:

mcs /reference:System.dll /reference:System.Windows.Forms.dll HelloForms.cs

results in the following stack trace:

>mono HelloForms.exe

Any ideas,
