title: Suddenly (since today) the shadow of markers is not displayed
body: <p>I have a Google Map with multiple markers coming from a database. The markers have an icon and a shadow, but since this morning the shadow is not dispalyed. If I debug the code and the objects with firebug everything seems to be ok. I tried this on several machines as well as on several browsers (Chrome, Firefox, IE).</p>
  
  <p>Has anyone a tipp what the problem could be.</p>
  
  <p>Thanks in advance...Guido</p>
