title: ItemAdded triggers three times
body: <p>I added an ItemAdded eventreceiver for a SharePoint document library programmatically and everything works fine on my computer. I checked in my code and my colleague got the latest code from our TFS, built the project and tested it.</p>
  
  <p>On my colleague's computer the ItemAdded event triggers three times when he adds a document from the SharePoint GUI.</p>
  
  <p>On my computer it only triggers once as it should.</p>
  
  <p>Have you seen something similar and do you know how to solve it?</p>
