Description

The line 4th line on the following code causes a crash on Mac OSX

using System;
using System.Windows.Forms;
 
public class HelloWorld : Form
{
  OpenTK.GLControl glControl = new OpenTK.GLControl();
 
  static public void Main()
  {
    Application.Run(new HelloWorld());
  }
 
  public HelloWorld()
  {
    Text = "Hello World";
 
  }
}

Here is the output:

Nice!

@kanato: this was the main issue indeed. Simply changing the order in the factory constructor set things right.
