Problem with Google Maps not zooming or able to move around

[system]

Hi,

I am having an issue with my google map code where it keeps on auto centering and wont let me zoom or move the map around.

Code:

$(document).ready(function(e) {
       initialize(); 
    });

var map = null;
var markersArray = [];
var markers = [];
var openedInfoWindow ="";
var geocoder = new google.maps.Geocoder();

 function initialize() {
        
		var mapOptions = {
          center: new google.maps.LatLng(-34.397, 150.644),
          zoom: 8,
          zoomControl: true,
          zoomControlOptions: {
            style: google.maps.ZoomControlStyle.SMALL
          },
          mapTypeId: google.maps.MapTypeId.ROADMAP
        };
        map = new google.maps.Map(document.getElementById("mapInfoManual"),
            mapOptions);
      
	  
		addMarker();	  
	  }
	  
	  
	  
	  
	  
function addMarker() {
	   	
	   	
		var bounds = new google.maps.LatLngBounds();
		for(i=0; i<markersArray.length; i++)
		{
			CodeAddress(markersArray[i]['address']);
		}
		setInterval(function()
		{
		  
		  for(i=0; i<markers.length; i++)
		  {
			  var point = new google.maps.LatLng(markers[i]['lat'], markers[i]['lng']);
			  
			  var marker = new google.maps.Marker({
				  position: point,
				  map: map
			  });
			  bounds.extend(point);
			  
			  openInfoWindow(marker,markersArray[i]['address'])			
		  }
		  map.fitBounds(bounds);

		  },1000);

}


// Address To Marker
function CodeAddress(address)
{
	
	geocoder.geocode( { 'address': address}, function(results, status) {
	if (status == google.maps.GeocoderStatus.OK) {
		lat = results[0].geometry.location.lat();
		lng = results[0].geometry.location.lng();
		markers.push({
						'lat':lat,
						'lng':lng,
						'address':address
					});
		
	} 
	
});	  
}


//Info Window
function openInfoWindow(marker,content)
{
	
	var infowindow = new google.maps.InfoWindow({
		content: '<div><p style=" color: #000000; font-size: 11px;">'+content+'</p></div>'
	});
	
	
	
	google.maps.event.addListener(marker, 'click', function() {
		
		if(openedInfoWindow !="")
		{
			openedInfoWindow.close()
		}

		
		infowindow.open(map,marker);
		openedInfoWindow = infowindow;
	});
}
