+Summary: Control.Invoke is broken (not synchronous)
+
+Description of Problem:
+
+Control.Invoke should wait for the action to complete (it is not 
+synchronous)
+
+Steps to reproduce the problem:
+1. Create a form, create a new thread, use Control.Invoke from the thread 
+and see if it is synchronous.
+
+
+using System;
+using System.Threading;
+using System.Windows.Forms;
+
+class M { 
+    static Form f;
+    static void Main() { 
+      f = new Form();
+      f.Paint += new PaintEventHandler(startThread);
+      Application.Run(f);
+    }
+    static void startThread(object sender, PaintEventArgs args) {
+      Thread t = new Thread(new ThreadStart(run));
+      t.Start();
+    }
+    static void run() {
+      f.Invoke(new MethodInvoker(run2));
+      Console.WriteLine("Should Come Second");
+    }
+    static void run2() {
+      Thread.Sleep(100);
+      Console.WriteLine("Should Come First");
+    }
+
+}
+
+Actual Results:
+
+Mono System.Windows.Forms Assembly [Revision: 54007; built: 2005/12/6 
+14:35:24]
+Should Come Second
+Should Come First
+
+
+Expected Results:
+
+Mono System.Windows.Forms Assembly [Revision: 54007; built: 2005/12/6 
+14:35:24]
+Should Come First
+Should Come Second
+
+
+How often does this happen? 
+
+Always
