title: Tortoisehg icons not showing
body: <p>I copied a repository (whole folder) from one computer to another and added the repository to the TortoiseHG workbench through File->Open Repository.</p>
  
  <p>Everything works fine, except no overlay icons are showing in windows explorer in the directory of the copied repository (for whether the file has been modified, or it's up to date, etc).
  Does anyone know how I can fix this?</p>
  
  <p>Thanks</p>
