Jose, 

I missed where you posted the rest of the code for the zooming.  Can you send that to me or post it again.  Or point me to the post that contains the code.

Chris

I've try to post the code in the internal list, but I don't how to register. Anyway here the code. I've applied the changes on the 1.0.2, but in the last version works fine.

Somebody who know how to do it, please e-mail me.

This patch use javascript to zoom with the wheel mouse, like in AutoCAD.

Another patch is to input in the scale bar, a scale manually. 

You can see an icon in the toolbar when the map is loading.

All these changes in action here <http://wms.diphuelva.es/mapguide/phpviewersample/index.php> . Click on the help icon to see more features.

E-mail me with any problem.

Thank you.

In css: 

________________________________

        div.cssRefresh
        {
            position: absolute; 
            right:10px;
            top:4px;        
        }

The body seems like this. Rotating_arrow.gif is the image. You can design it or use the attached:

________________________________

<body class="Toolbar" onload="InitDocument()" leftmargin=10 topmargin=0 rightmargin=0 bottommargin=0 marginwidth=0>
    <div id="divRefresh" name="divRefresh" class="cssRefresh"><img alt="loading" src="../phpviewersample/images/common/rotating_arrow.gif"></div>
    <span id="ToolbarContent"><td></td></span>
    <div class="TextMetricsDiv" id="TextMetricsDiv"><span class="TextMetrics" id="Metrics"></span></div>
  </body>
