Circles is superimposing Merkers by making clicks impossible (Google maps Javascript API)

Question

In Google maps API Javascript, when using the Circles object it overlaps my Layer of Fusion Tables and makes it impossible to click on the markers and open the infowindow etc of each Mac.

I have tried calling Circle before the fusion Tables call, without success. I also tried putting Zindex in the markers and continued the same thing..

NOTE: When I use a normal non-layer Marketer, Marker is on top of Circle and works normal.. only the layer that is below Circle. Follow a screenshot demonstrating the Circle overlay relative to the layer’s Marketer:

And follow a piece of code showing the calls:

	circle = new google.maps.Circle({
      strokeColor: '#0000ff',
      strokeOpacity: 0.4,
      strokeWeight: 1,
      fillColor: '#0000ff',
      fillOpacity: 0.07,
      map: map,
      center: myLocation,	
      radius: radius
    });

    //camada  do fusion table
    layer = new google.maps.FusionTablesLayer({
	    query: {
	      select: '\'Location\'',
	      from: tableId,
	    styles: [{
		      markerOptions: {
				    iconName: "ylw_stars",
				    zIndex:999
				  }
		    }
			],
		  map: map
	  });
