title: Toolstrip is flashing - blanking
body: <p>I use :
   - Windows 7<br>
   - VS2010 SP1<br>
   - Framework 4<br>
   - Winforms<br>
   - MDI Parent<br>
   - StatusStrip</p>
  
  <p>My main form is MDI parent with a StatusStrip that contains 6 StatusLabels.<br>
  When the main form is maximised, the tooltips from the StatusStrip start flashing.
  It only seems to happen when the form is maximised.<br>
  I am thinking if it has to do with the operating system task bar and the space between them.<br>
  The code that I use is very simple :</p>
  
  <pre><code> Me.lblServer.ToolTipText = myServer.Name 'lblServer is a StatusLabel
  </code></pre>
  
  <p>I tried also to set the tooltip by myself in lblServer_MouseHover:</p>
  
  <pre><code> ToolTip.SetToolTip(lblServer, myServer.Name)
  </code></pre>
  
  <p>but lblServer is not a control, so it is impossible to do it that way.<br>
  Does anyone have an idea how to work around this problem?</p>
  
  <p>Thanks</p>
