title: Google Map v3 - MarkerWithLabel. Label dont exist in IE9
body: <p>I'm porting Google Map from v2 api to v3. Of course I encountered a problem. I use MarkerWithLabel() to create markers with title. In every browsers (even in IE8) except IE9 labels are visible. Where could be a problem?</p>

  <p>This is my code of marker with laber builder function:</p>
  
  <pre><code>function createRegionMarker(pointData) {
      var latlng = new google.maps.LatLng(pointData.lat, pointData.lng);
      var image = new google.maps.MarkerImage("/images/rall.png", new google.maps.Size(40, 40), new google.maps.Point(0,0), new google.maps.Point(0, 32));
  
  var marker = new MarkerWithLabel({
      position: latlng,
      icon: image,
      clickable: true,        
      draggable: false,
      map: map,
      labelContent: pointData.id,
      labelAnchor: new google.maps.Point(-10, 20),
      labelClass: "map-labels",
      labelInBackground: false
  });
  
  google.maps.event.addListener(marker, "click", function() {
          zoomMarker(pointData.lng, pointData.lat, 8);
  });
  
  return marker;
  }
  </code></pre>
