[OpenLayers-Users] Markers disappear at High Zoom Levels

[Obe, Regina]

I'm using version 2.3 stable of OpenLayers and am experiencing the same problem as described here
 
http://openlayers.org/pipermail/users/2007-January/000514.html
 
It seems that no matter what I try, my markers disappear around Zoom 15.  Is there a solution for this.
 
 
My map code looks something like
 var lon = -71.0891380310059
 var lat = 42.3123226165771
 
     var options = { 
    maxZoomLevel: 20,
    maxResolution: "auto",
    numZoomLevels: 20, 
  controls: [new OpenLayers.Control.MouseDefaults(), new OpenLayers.Control.PanZoomBar(), new OpenLayers.Control.MouseToolbar()]
   };
    var map = new OpenLayers.Map(document.getElementById("map"), options);
 
    var boston = new OpenLayers.LonLat(lon,lat);
    map.setCenter(boston, 14);
 
 var gmaerial = new OpenLayers.Layer.Google("Google Hybrid", { 'type': G_HYBRID_MAP });
 map.addLayer(gmaerial);
 
 var markers = new OpenLayers.Layer.Markers("Markers", {numZoomLevels:17, maxZoomLevel:17, minZoomLevel: 10});
 map.addLayer(markers);
 
 var size = new OpenLayers.Size(10,17);
 var offset = new OpenLayers.Pixel(-(size.w/2), -size.h);
 var icon = new OpenLayers.Icon(OpenLayers.Util.getImagesLocation() + 'marker-blue.png',size,offset);
 var marker0 = new OpenLayers.Marker(new OpenLayers.LonLat(lon, lat),icon);
markers.addMarker(marker0);
 
 
Thanks,
Regina
