title: wpf tooltip on mouseover and mouseout
body: <p>What I am trying to do is have the tool tip show once a mouse over occurs.  The ToolTip will not turn off until a mouse out. </p>
  
  <p>Only a mouse out will allow the ToolTip to close. </p>
  
  <p>The customer has a requirement where they want the ToolTip to stay up indefinite until a mouse out happens. </p>
  
  <p>Additional:  Is there a way only to close the tooltip on mouse out, and not mouse move? </p>
  
  <p>The area that the mouse will be over is a rectangle and only when I move out of the rectangle should the tool tip close. </p>
  
  <p>Thanks.</p>
