Hello,<br>I have a map and when I zoom using the mouse wheel the map zooms by 2 zoom levels instead of 1 when I move the mouse wheel slightly.<br><br>instead if I double click the map or click up or down on the zoom control it zooms in or out by 1 zoom level.<br>
<br>Here is the relevant code:<br><br>map = new OpenLayers.Map(<br>                    &#39;map&#39;,<br>                    {<br>                        &#39;maxResolution&#39;:&#39;auto&#39;,<br>                        &#39;tileSize&#39;:new OpenLayers.Size(200,200),<br>
                        maxExtent: new OpenLayers.Bounds(-180, -90, 180, 90),<br>                        controls:[<br>                            new OpenLayers.Control.Navigation(),<br>                            new OpenLayers.Control.ArgParser(),<br>
                            new OpenLayers.Control.Attribution(),<br>                            new OpenLayers.Control.PanZoomBar({ position: new OpenLayers.Pixel(2, 15) }),<br>                            new OpenLayers.Control.Navigation(),<br>
                            new OpenLayers.Control.Scale($(&#39;scale&#39;)),<br>                            new OpenLayers.Control.LayerSwitcher(),<br>                            new OpenLayers.Control.MousePosition(),<br>
                            new OpenLayers.Control.Permalink()<br>                        ]<br>                    }<br>                );<br>                <br>                layer0 = new OpenLayers.Layer.WMS(<br>                    &quot;CIRA Base Layer&quot;, urlArray,<br>
                    {<br>                        layers:&#39;cira_base&#39;,<br>                        format:&#39;image/png&#39;,<br>                        bgcolor: &#39;#99B3CC&#39;<br>                    },<br>                    {singleTile:false, transitionEffect: &#39;resize&#39;}<br>
                );<br><br clear="all">map.addLayers([layer0]);<br>                <br>                map.zoomToMaxExtent();<br>                <br>                map.setCenter(new OpenLayers.LonLat(-100.42306,40.35960),1);<br>
<br>Any ideas as to why this would be happening?<br><br>thank you very much!<br><br>-- <br>Signed,<br>Alessandro Ferrucci<br>
