Hi,<br><br>While using the openlayers map with yahoo base layer, if you pan (move around) across the map after a while you get a JavaScript error. This happens only in Internet Explorer (6 and 7).<br><br><b>The error reads</b>: "Invalid Argument"<br>
<b>Line number</b>: 579 in OpenLayers.js<br><br><i><b>After enabling script debugging, the browser pointed at this line:</b></i><br>this.dragging=!!dragging;},centerLayerContainer:function(lonlat){var originPx=this.getViewPortPxFromLonLat(this.layerContainerOrigin);var newPx=this.getViewPortPxFromLonLat(lonlat);if((originPx!=null)&&(newPx!=null)){this.layerContainerDiv.style.left=Math.round(originPx.x-newPx.x)+"px";this.layerContainerDiv.style.top=Math.round(originPx.y-newPx.y)+"px";}},isValidZoomLevel:function(zoomLevel){return((zoomLevel!=null)&&(zoomLevel>=0)&&(zoomLevel<br>
<br>Anyone knows why this is happening and how to get around the problem?<br><br>Regards,<br>Vishwa<br><br><br><br>
