title: Why does vb.net Datetimepicker fires a 'GLOBAL WINDOWS HOOK' on Windows 7?
body: <p>I have a vb.net Winform Application with a DatetimePicker Control.</p>
  
  <p>Installed 'Zone Alarm' Firewall. </p>
  
  <p>Whenever I Click the Dropdown Button on the Datetimepicker Control, Zone Alarm pops up a message that "This Application is attempting to Monitor User Activities,..etc". 
  The Logs in the Zone Alarm says "GLOBAL WINDOWS HOOK" is made.</p>
  
  <p>It alerts in Windows 7 and not in Windows XP.</p>
  
  <p>Why does Datetimepicker attempt for a Global Hook in Windows 7?</p>
