A simple multi-threaded application using Gtk# under windows freezes when any window is moved, while using the Gdk.Threads components.

Here is a very simple example that hangs when the window is moved, the label and the button are only meant to prove that otherwise Gtk# is operating properly.

using System;
using Gtk;

namespace FreezingWindow
    class MainClass
        public static void Main (string[] args)
            if (GLib.Thread.Supported) {
                GLib.Thread.Init ();

            Gdk.Threads.Init ();

            Gdk.Threads.Enter ();
            Application.Init ();
            Window win = new Window ("test");

            var box = new VBox ();

            var label = new Label ("Test");
            box.PackStart (label);

            var btn = new Button ("Test");
            btn.Clicked += delegate(object sender, EventArgs e) {
                label.Text = DateTime.Now.ToString();
            box.PackStart (btn);

            win.Add (box);
            win.ShowAll ();
            Application.Run ();
            Gdk.Threads.Leave ();
