Hi Denis, thanks for your answer. addBuilding is a custom function that creates
a vector on the vector layer with a special icon. I already use vectors instead
of markers, apologies for my unclear description. I do have a vector layer and
place different vectors of OL.Features.Vector on it. But I can't get the
clustering work so far. The only difference between your code and mine is that
you add 'autoactivate: true' to your Cluster constructor, I don't know if this
is mandatory for the clustering to work, I will test it on Monday. Any other
comments on that? I really appreciate your fast and competent answer! Regards

clustering work Hi! What is addBuilding function? I'm not sure about cluster
strategy may be used with markers. I'm prefer to use features, because markers
are deprecated: <html><body>
<div id="mapdiv"></div>
<script
src="http://openlayers.org/dev/OpenLayers.js"></script>
<script>
map = new OpenLayers.Map("mapdiv");
map.addLayer(new OpenLayers.Layer('', {isBaseLayer: true, maxExtent: new
OpenLayers.Bounds(-200,-200,200,200)}));
var buildingLayer= new OpenLayers.Layer.Vector("Buildings",
{maxExtent: new OpenLayers.Bounds(-200,-200,200,200),
strategies: [new OpenLayers.Strategy.Cluster({autoActivate: true,
distance: 100})]
});
map.addLayer(buildingLayer);
buildingLayer.addFeatures([new OpenLayers.Feature.Vector(new
OpenLayers.Geometry.Point(-50.126,36.755)),
new OpenLayers.Feature.Vector(new
OpenLayers.Geometry.Point(-100.196,43.215)),
new OpenLayers.Feature.Vector(new
OpenLayers.Geometry.Point(-150.556,56.615)),
new OpenLayers.Feature.Vector(new
OpenLayers.Geometry.Point(-170.423,35.510))]);
map.zoomToMaxExtent();
