title: ASP.NET AJAX ToolKit: Numeric MaskedEditExtender issue
body: <p>I have an AJAX ToolKit MaskedEditExtender control:</p>
  
  <pre><code>&lt;asp:TextBox ID="payRateTextBox" runat="server" 
      CssClass="valueControl"&gt;&lt;/asp:TextBox&gt;
  
  &lt;asp:MaskedEditExtender ID="payRateMaskedEditExtender" runat="server" 
      AcceptNegative="Left" InputDirection="RightToLeft" 
      Mask="999.99" MaskType="Number" 
      TargetControlID="payRateTextBox"  /&gt;
  </code></pre>
  
  <p>Empty text looks like the following when it gets focus:</p>
  
  <blockquote>
    <p><em><strong></em>__<em>_</em>_</strong>.<em>_</em>_</p>
  </blockquote>
  
  <p>The problem is the extender dosent allow user to enter a 0 as the first entered character in the first digit at the left of the point (Where the X resides) ..</p>
  
  <blockquote>
    <p><em><strong></em>___</strong><em>X.</em>___</p>
  </blockquote>
