[OpenLayers-Users] problem with re positioning of icons after zoom in and zoom out.

[Vinay BM]

Hello All,

I have some problem with re positioning of icons on different layers.

I have added 2 layers and 3 icon layers to the main base layer.
after performing zoom in and zoom out operation for nearly 2 to 3 times. the 
icons are changing it's position. once i refresh, the icons would be in a 
original place.

here is the code 

var extent = new OpenLayers.Bounds(10, -90, 60, 90);
        
        var bigZoom = new OpenLayers.Control.PanZoomBar();
        var smallZoom = new OpenLayers.Control.PanZoom();
        
        map = new OpenLayers.Map(elementId, { 
                controls: [
                        new OpenLayers.Control.Navigation(), 
                        bigZoom, 
                        smallZoom,
                        new OpenLayers.Control.OverviewMap()],
                        restrictedExtent : extent
        });
        

        map.zoomControl = {
                big: bigZoom,
                small: smallZoom
        };
        
        addBaseLayer();
        addPhysicalLinkLayer();
        addLayer("CONTAINERs", contextPath + "/images/ne_SISA_graphical32.gif");
        addLayer("NEs", contextPath + "/images/netypes/" + "${neType}" + 
"_white32.png");
        addIconLayer('alarms' , '/images/alarms/' + '${severity}' + '16.gif' , 
-25 , -21);
        addIconLayer('maintanence' , '/images/maintanence/' + '${severity}' + 
'16.gif' ,-25 , 0);
        addIconLayer('communicationstate' , '/images/communicationstate/' + 
'${severity}' + '16.gif' , 12 , 0);
        addDragFeature();
        addSelectFeature();
        
        updateMapControls();
        
        map.zoomToExtent(extent);
        map.setCenter(new OpenLayers.LonLat(70,78.74603), 2);
        
        map.attributes = [];
        map.dragging = false;
        map.lastToolTipEvent = null;
        map.toolTipDelay = 1000;
        map.toolTipVisibilityTime = 5000;
                

please suggest your opinion.

Thank you and Regards,
Vinay.
