Cause

This problem occurs because of behavior that occurs when you use the AttachEvent method. When you do this, the interface pointer that is referenced by the spreadsheet control may be released before the control is completely shut down. When this problem occurs, Internet Explorer cannot release the pointer after the pointer has already been released. For example, this problem occurs when you use code that resembles the following example.
<script type="text/javascript">
function onSheetChange (Sh, Target)
{
  alert ('R' + Target.Row + 'C' + Target.Column + ' changed to: ' + Target.Value);
}
document.getElementById('SpreadSheet1').attachEvent('sheetchange', onSheetChange);
</script>

Resolution

To resolve this problem, use attributes instead of events in the code for the application. Then, try running the application again. For example, use code that resembles the following code example.
<script type="text/javascript" for="SpreadSheet1" event="sheetchange(sh,Target)">
alert ('R' + Target.Row + 'C' + Target.Column + ' changed to: ' + Target.Value);
</script>
