title: Using launcher app and stack - loss of datagrid data
body: <p>I followed the lessons on how to use a launcher stack with the main stack being seperate in order to be able to save data when you save the stack. </p>
  
  <p>However, I now have the situation where my launcher does a quick check on a text file on the web server to verify the version number, and if required, downloads a new version of the main stack. </p>
  
  <p>Problem is now, that all data in datagrids are then "erased" because it is a "new" stack. </p>
  
  <p>So the only sensible answer is to store data in seperate files anyway because the main stack cannot  store its own data and retain it? Or am I missing something very basic here?</p>
  
  <p>How can i do this ?</p>
