title: Sencha cmd not opening
body: <p>Hi I want to learn Sencha. I have basic knowledge of MVC. I have downloaded <a href="http://www.sencha.com/products/touch/" rel="nofollow">sencha Touch</a> and <a href="http://www.sencha.com/products/sencha-cmd/download" rel="nofollow">Sencha cmd</a>. I have extracted <code>sencha Touch</code> folder to my local. And I have installed Sencha cmd. But <code>Sencha cmd</code> is not working. When I click on <code>cmd</code> it automatically disappeared. What can I do now. I have installed <code>Sencha SDK Tool</code>. </p>
  
  <p>Any one please help me out.</p>
