title: Browser Helper Object Issue: setsite/getsite not called on one machine
body: <p>I have developed a Managed Browser Helper Object (BHO). This works on all machines except one.</p>
  
  <p>I have ensured that protected mode is off and UAC is also turned off on this machine.</p>
  
  <p>This particular machine is Win Vista with IE 8.</p>
  
  <p>I added some debug logs and message box in GetSite and Setsite. I do not see these logs or message box. I am assuming that these are not being called for some reason.</p>
  
  <p>Is there some better way to debug my problem?</p>
  
  <p>Thanks</p>
