title: Mousehover, tooltip showing multiple times
body: <p>I have a custom control (C#, visual studio).  I want to show a tooltip on the mousehover event.</p>
  
  <p>However, no matter what I do, it either never shows or has a chance of showing multiple times.</p>
  
  <p>I thought it would be as simple as:</p>
  
  <pre><code>private void MyControl_MouseHover(object sender, EventArgs e)
  {
      ToolTip tT = new ToolTip();
  
      tT.Show("Why So Many Times?", this);
  }
  </code></pre>
  
  <p>But this does not work.  I have tried a bunch of things but cannot seem to get it to work.  I would like to have the tooltip be part of the component because I want to access private fields from it for display.</p>
  
  <p>Thanks for any help</p>
