title: Timer doesn't want to start again after it was disabled
body: <p>I am writing a simple C# program that attempts to do something every x amount of seconds using System.Forms.Timer</p>
  
  <p>The tick event calls a method that starts a new thread and disables the timer, then when the thread is done with its work, it enables the timer again, but the problem is, now it doesn't tick after it's been enabled.</p>
  
  <pre><code>static System.Windows.Forms.Timer testtimer = new System.Windows.Forms.Timer();
  
      static void Main()
      {
          testtimer.Tick += testtimertick;
          testtimer.Interval = 5000;
          testtimer.Enabled = true;
          testtimer.Start();
  
          while (true)
          {
              Application.DoEvents();  //Prevents application from exiting
          }
  
      }
  
   private static void testtimertick(object sender, System.EventArgs e)
      { 
  
              testtimer.Enabled = false;
              Thread t = new Thread(dostuff);
              t.Start();
      }
  
  
  private static void dostuff()
      {
  
         //Executes some code
         testtimer.Enabled = true; //Re enables the timer but it doesn't work
         testtimer.Start();
       }
  </code></pre>
