title: Tooltip not showing when hovering
body: <p>A simple piece of code.  I notice that when I hover over a '*', the tooltip doesn't show.</p>
  
  <p>Are Tooltips working in Internet Explorer 10?</p>
  
  <p>Code:</p>
  
  <pre><code>&lt;p&gt;Username:&lt;asp:TextBox ID="UsernameTextBox" runat="server"&gt;&lt;/asp:TextBox&gt;&lt;/p&gt;
  &lt;asp:RequiredFieldValidator ID="UsernameRequiredFieldValidator" runat="server"
       ErrorMessage="Your Username is Required" ControlToValidate="UsernameTextBox" 
       Text="*"&gt;
  &lt;/asp:RequiredFieldValidator&gt;
  &lt;asp:RegularExpressionValidator ID="UsernameRegularExpressionValidator" runat="server" 
       ErrorMessage="Please only use letters and numbers with no spaces." 
       ControlToValidate="UsernameTextBox" Text="*" 
       ToolTip="Please only use letters and numbers with no spaces." 
       ValidationExpression="\w{6,14}"&gt;
   &lt;/asp:RegularExpressionValidator&gt;
  </code></pre>
  
  <p>Regards,</p>
