title: Balloon not showing up with NotifyIcon.ShowBalloonTip
body: <p>I'm having trouble with something that I thought would be easy...
  I can't get my NotifyIcon to show a balloon tip.  The basic code is:</p>
  
  <pre><code>public void ShowSystrayBubble(string msg, int ms)
  {
    sysTrayIcon.Visible = true;
    sysTrayIcon.ShowBalloonTip(20, "Title", "Text", ToolTipIcon.None);
  }
  </code></pre>
  
  <p>Nothing happens when I execute this code.  I read that the timeout arg may be in seconds or ms, can't tell, so I tried both and neither works.</p>
  
  <p>I'm using WinXP, .NET 3.5.</p>
