title: Keydown event does not seem to work
body: <p>I'm working on a reactiontest. When I copied my project into some other project (with a menu etc.) the timer and Keydown did not work. My friend solved the timer with a Eventhandler, but the keydown still does not work.</p>
  
  <pre><code>private void Button1_KeyDown(object sender, KeyEventArgs e)
      {
          char c = Convert.ToChar(e.KeyCode);
          if (c == 82)
          {
              this.BackColor = Color.LightBlue;
              extime.Stop();
              long rtime = extime.ElapsedMilliseconds;
              timer1.Enabled = false;
              button1.Text = Convert.ToString(rtime) + Environment.NewLine + "milliseconds";
              button1.Visible = true;
              extime.Reset();
          }
      }
  </code></pre>
  
  <p>this did not work:</p>
  
  <pre><code>private void Reactiontest_Load(object sender, EventArgs e)
      {
          button1.KeyDown += Button1_KeyDown;
      }
  </code></pre>
