I believe that's commonly called a Dr. Watson. You can find more details on the error in the event viewer (under applications). You can find the event viewer under the control panel.

But, basically, it appears to be some JavaScript code is causing IE's JS engine to crash. Can you post which exact version of IE you're using (help menu -> About Internet Explorer)? And let us know if it works or fails with other versions of IE.

this error appears in both IE versions 6(6.0.2900.2180.xpsp_sp2_rtm.040803-2153) & 7(7.0.5730.13).

obj.setCellFormat is usually coded in conjunction with setCellData and you'r using obj.setCellText(myData);

Is myData defined elsewhere ?

I get a Runtime Error! R6025 -pure virtual function call when I run your sample, but only if I am doing the onblur event over the input more than once in the same second ( or 1,5 seconds), so I think it is related to trying to do a refresh while still doing a previous refresh ( and unfinished the rendering action).
I suggest to apply the refresh only once , doing something like:

<input id="Text1" type="text" onblur="DoMyRefresh();"/>
<script type="text/javascript">
var isstillrefreshing = false;

function DoMyRefresh(){
isstillrefreshing = true;
if (!isstillrefreshing){obj.refresh()}
if (isstillrefreshing){alert( 'still refreshing, Please wait a second and try again')} 
isstillrefreshing = false;
} 
// create ActiveWidgets Grid javascript object
var obj = new AW.UI.Grid;
//. . . . . . . ..

IE may crash if you destroy the focused element inside onfocus/onblur events. I guess this is what happens in your case - you move focus into the grid and at the same time refresh the grid (destroying and recreating the focused element).

As a workaround try grid refresh after some timeout, when blur/focus events are already completed.
