SetColSorting does not work in IE11.(pro3.5)

Hi. Nice to meet you. I’m a user that is using the grid as dhtmlx.(pro3.5 120731)
(I can not speak English.
So I’m writing through the Google translator.
So I could be wrong grammar)

sorting is not in ie11.
(FF,crom,ie7~10 all no problem.)

before click

after click

<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>

      		<div id="gridbox" style="width:100%;"></div>
<script>

	mygrid.setHeader("<input type='checkbox' id='chk' onclick='chkAll()' />,제목,날짜,작성자,첨부파일");
	mygrid.setInitWidthsP("4,68,10,10,7");
	mygrid.setColAlign("center,left,center,center,center");
	mygrid.setColTypes("ch,ro,ro,ro,ro");
	mygrid.setColSorting("na,str,str,str,na");
	mygrid.enableMultiline(true);

	mygrid.init();
	mygrid.setSkin("dhx_skyblue");
	mygrid.enableSmartRendering(true, 50);


	mygrid.clearAndLoad(xmlurl);

   dhtmlxError.catchError("LoadXML",function(a,b,data){
	});
   </script>

Please help me~ ;-(
bye bye~

You need to update dhtmlx to 4.0 or later
DHTMLX Suite 3.5 doesn’t support IE 11

Unfortunately, there is no separate fix for the above issue in IE11.

I probably bought the pro 3.0 version .
( My version now is 3.5 . I remember those who received once upgrade )
(buy license : Commercial License)

In order to upgrade to 4.0 , I would need to buy again ?
Or can be applied additional upgrade to an existing target buyers ? ( it take how much cost if any)

Answer please . Thank You

Please drop an email to sales@dhtmlx.com, they will provide all necessary info.
