title: close active infowindows from external link google maps api v3
body: <p>I am working on a website with google maps integrated.
  <a href="http://www.ecompanies.nl/pilot/webdesign/breda.html" rel="nofollow">http://www.ecompanies.nl/pilot/webdesign/breda.html</a></p>
  
  <p>Infowindows can be opened by clicking on a map marker, or on a header link in the items listed on the right. How can I close the active infowindow before opening a new one (by clicking on a map marker, or on a header link)?</p>
  
  <p>Thanks in advance.
  Any help is highly appreciated.</p>
