Unable to mark/select values in header text-boxes

Hi,
In IE,
For an XML object parsed dhtmlxGrid,
When attaching a grid header with input fields in it,
It’s impossible to mark/select the values entered to it as customary in most input fields.
(Try double click on the text in the input field in the header).
Do you have any suggestion how to solve this?
(Attached please find a sample code.)

Thanks.

Sample code:

Loading from XML
</head>
<body>
    <div class="content">
 <link rel="STYLESHEET" type="text/css" href="../../codebase/dhtmlxgrid.css">
<link rel="stylesheet" type="text/css" href="../../codebase/skins/dhtmlxgrid_dhx_skyblue.css">
<script  src="../../codebase/dhtmlxcommon.js"></script>
<script  src="../../codebase/dhtmlxgrid.js"></script>		
<script  src="../../codebase/dhtmlxgridcell.js"></script>
<script  src="../../codebase/ext/dhtmlxgrid_mcol.js"></script>
<script  src="../common/data.js"></script>	


<p>Load data from xml file</p>
<div id="gridbox" style="width:400px; height:270px; background-color:white;"></div>
<br><br>
<br>
<textarea id ="xml_text" name="xml_text" style="display:none;">
		<rows>
				<row id = "1">
						<cell>0</cell>
						<cell>1 loaded from xml object</cell>
				</row>
				<row id = "2">
						<cell>1</cell>
						<cell>2 loaded from xml object</cell>
				</row>
				<row id = "3" selected = "1">
						<cell>2</cell>
						<cell>3 loaded from xml object</cell>
				</row>
		</rows>
</textarea>
</div>
</body>

I’ve got the same problem. Could anybody help with this problem?

The answer I got at last was this:

Selection is blocked in grid by default, to re-enable it use

grid.entBox.onselectstart=function(){
return true;
};

It works for me.
