<input id='inptst' value='tstval'>
<script language='javascript' type="text/javascript">
var s=document.getElementById('divtst').innerHTML;
document.write(document.getElementById('inptst').innerHTML);
</script>


Actual results:

returned a string from prior innerHTML


Expected results:

expected undefined

Sorry my snippet there doesn't do it reliably, but something similar must.
This is what I get from my console:-

11:54:37.392 aDstFn[0].innerHTML
11:54:37.398 "DCN:38855"
11:55:16.387 aDstFn[0].outerHTML
11:55:16.392 "<input id="Scr_SEditTxt:42_O" class="edit" value="1025 - Z - Mark Merrick" onchange="SEditTxtUpd(this,3);">"

Can I delete this bug - I've just realised I must have set the innerHTML on it inadvertantly, hence the results - doh...
