Hi. Do you have maxExtent set in your map options? OpenLayers shouldn't request tiles outside the max extent. If it does it's a bug in OpenLayers. Another guestion: what layer type do you use? Layer.MapServer or Layer.WMS? If you use the former, make mapserver work as a WMS server and try using Layer.WMS to see if that fixes the problem. Again the ideal would be some example so that we con easily reproduce your problem. Eric
