title: Google Maps: Auto close open InfoWindows?
body: <p><a href="http://www.uptownelite.com/test.html?city=dallas,tx" rel="noreferrer">On my site</a>, I'm using Google Maps API v3 to place house markers on the map.</p>
  
  <p>The InfoWindows stay open unless you explicitly click the close icon. Meaning, you can have 2+ InfoWindows open at a time if you hover over the map marker.</p>
  
  <p><strong>Question</strong>: How do I make it so that only the current active InfoWindow is open and all other InfoWindows are closed? Meaning, no more than 1 InfoWindow will be open at a time?</p>
