title: TFS 2010 and MS Project 2010 refresh work item issue
body: <p>When choosing which work items to import (through the Get Work Items option) to my newly created MS Project file I've accidentally checked a work item that shouldn't be imported.</p>
  
  <p>I've removed this work item from my project file, but every time I click "Refresh" the work item appears again???</p>
  
  <p>Is this the correct behavior? I can NEVER bring a work item and later decide to remove it from the project file without it coming back?</p>
