title: Keep Tooltip Open when Mouse Hover
body: <p>I created a ribbon in WPF using .NET 4.0 framework.  I am trying to make use of <em>ToolTipTitle</em>, <em>ToolTipDescription</em> and <em>ToolTipFooterDescription</em>.  Since my tooltips will have hyperlinks, how can I make it so that when the mouse hovers over the tooltip, the tooltip stays open?</p>
  
  <pre><code>&lt;rib:RibbonMenuButton ToolTipTitle="Title" ToolTipDescription="My Description" ToolTipFooterDescription="My Footer With a Link"&gt;
  </code></pre>
  
  <p>A good example of this functionality is with Microsoft Excel.  When you hover over a ribbon button, an advanced tool tip will display to the user, and if the user hovers over the tooltip, it will remain open.  I am trying to mimic that functionality.</p>
