Form::Activate doesn't bring the window to the front and when forms are
activated (by clicking on a deactivated form for example) the activate and
deactivate events don't fire.

Here's a test case:

// compile with: 
// gmcs -r:System.Windows.Forms.dll -out:app.exe FormActivation.cs
using System;
using System.Collections.Generic;
using System.Diagnostics;
using System.Windows.Forms;

internal class Program
{
    public static void Main(string[] args)
    {         
        DoInit();

        Application.Run();
    }

     public static void DoInit()
     {         
        ms_timer = new Timer();

        DoCreateForm();
        DoCreateForm();

        ms_timer.Tick += DoTransition;
        ms_timer.Interval = 3000;
        ms_timer.Start();
    }

    private static void DoCreateForm()
    {
        Form form = new Form();
        form.Text = "window " + ms_forms.Count;
        form.Menu = new MainMenu();

        form.Activated += DoActivated;
        form.Deactivate += DoDeactivated;

            MenuItem fileMenu = new MenuItem("File");
            fileMenu.MenuItems.Add(0, new MenuItem("Quit", (s, e) =>
DoQuit()));

            form.Menu = new MainMenu();
            form.Menu.MenuItems.Add(fileMenu);

        form.Visible = true;

        ms_forms.Add(form);
    }

    private static void DoActivated(object sender, EventArgs e)
    {
        Form f = (Form) sender;
        Console.WriteLine("activated {0}", f.Text);

        ++ms_activateCount;
    }

    private static void DoDeactivated(object sender, EventArgs e)
    {
        Form f = (Form) sender;
        Console.WriteLine("deactivated {0}", f.Text);

        ++ms_deactivateCount;
    }

    private static void DoTransition(Object myObject, EventArgs myEventArgs) 
    {
        if (ms_state == 0)
        {
            Console.WriteLine("0) activating form 0");
            ms_forms[0].Activate();        
            ms_state = 1;
        }
        else if (ms_state == 1)
        {
            Console.WriteLine("1) activating form 1");
            ms_forms[1].Activate();
            ms_state = 2;
        }
        else
        {
            Console.WriteLine("2) checking");

            // Should be one (or maybe even two activates on startup) plus two
from the timer.
            // Should be zero (or maybe one deactivate on startup) plus two
from the timer.
            if (ms_activateCount >= 3 && ms_deactivateCount >= 3)
            {
                Console.WriteLine("passed: got {0} activates and {1}
deactivates", ms_activateCount, ms_deactivateCount);
            }
            else if (ms_activateCount < 3 && ms_deactivateCount < 2)
            {
                Console.WriteLine("FAILED: expected at 3-4 activates, but got
{0} activates", ms_activateCount);
                Console.WriteLine("FAILED: expected at 2-3 deactivates, but got
{0} deactivates", ms_deactivateCount);
            }
            else if (ms_activateCount < 3)
            {
                Console.WriteLine("FAILED: expected at 3-4 activates, but got
{0} activates", ms_activateCount);
            }
            else if (ms_deactivateCount < 2)
            {
                Console.WriteLine("FAILED: expected at 2-3 deactivates, but got
{0} deactivates", ms_deactivateCount);
            }

            DoQuit();
        }
    }

    private static void DoQuit()
    {
         foreach (Form f in ms_forms)
            f.Close();
          ms_forms.Clear();

         ms_timer.Stop();
         Application.Exit();
    }
