title: Why does Eclipse update the workbench.xmi file every five minutes?
body: <p>I have <code>DropBox</code> on my machine at home and on my work PC.  I also have Eclipse installed on my home PC.  I put all of the workspace files in my DropBox account for a few different reasons.</p>
  
  <p>Anyway, at work, I notice that DropBox notifies me every 5 minutes that the <code>workbench.xmi</code> file has been updated.  I realized that I left Eclipse running at home.  This is very annoying.</p>
  
  <p>Upon inspection, it looks like Eclipse is changing the ID's of all (or most) of the components.  Doing a diff on the file every 5 minutes revealed this.</p>
  
  <p>Is there a way to prevent Eclipse from doing this?  Other than remembering to shut it down, of course.</p>
  
  <p>I can't remember the version of Eclipse but I can find out if it's important.  I believe it's the newest version.</p>
  
  <p>Thanks.</p>
