Error type clipboard chrome

Hello,
I have problems with the Grid clipoard and Google Chrome.

<script>
function copyData() {
        mygridEmail.gridToClipboard();
}
</script>

<a href="javascript:void(0)" onclick="copyData()">
	<span>
		<img src="../../../4Data/plugin/dhtmlx/dhtmlx/dhtmlxToolbar/samples/common/imgs/copy.gif" />
		&nbsp;Copy
	</span>
</a>
<div id="gridEmais" style="height:150px; width:600;"></div>
<script>
	var mygridEmail = new dhtmlXGridObject("gridEmais");
	mygridEmail.enableEditEvents(false, false, false);
	mygridEmail.enableSmartRendering(true,7);
	mygridEmail.init();
	mygridEmail.setSkin("dhx_skyblue");
	mygridEmail.loadXML("<%=URLHTTP%>/xml/getXML.asp?action=getEmailsCasos&cd_Caso=<%=cd_Caso%>");
</script>

Could anyone help me?

Unfortunately it impossible to enable clipboard operations in Chrome programatically.
