title: Weblogic Workshop asks to upgrade projects everytime
body: <p>I am using the Weblogic Workshop for Portlet development.  It's built on Eclipse.  I upgraded my Eclipse from 3.2 to Weblogic Workshop. 
  The problem is that everytime I start the Workshop it gives me an upgrade information that I need to upgrade my projects as they were created with older version of Eclipse.<br>
  This should have to be done only once, right?  Not everytime.  Is there a solution?</p>
  
  <p>Text of message:</p>
  
  <p>"Upgrade projects created with older release of Eclipse and/or related plugins."</p>
  
  <p>Thanks,</p>
