title: Blinking Tooltip
body: <p>I am using a tooltip on a listbox and although it works it keeps flickering/blinking any idea's how to fix this?
  The only thing i could think of was turning on double buffering but that didn't work.</p>
  
  <p>this is the function i use;</p>
  
  <pre><code>private void onMouseMove(object sender, MouseEventArgs e)
  {
      if (sender is ListBox)
      {
          Point point = new Point(e.X, e.Y);
          int hoverIndex = LSB_OfflineVars.IndexFromPoint(point);
          if (hoverIndex &gt;= 0 &amp;&amp; hoverIndex &lt; LSB_OfflineVars.Items.Count)
          {
              tt.SetToolTip(LSB_OfflineVars, LSB_OfflineVars.Items[hoverIndex].ToString());
          }
      }
  }
  </code></pre>
  
  <p>Thanks in advance,
  Robin</p>
