How to re-produce the "black screen with cursor before login" issue

I came into this two days ago and it has given me a really hard time to figure out a fix.
it turned out though, the cause of my issue was probably bit different: I have two video output from the computer connect to the same monitor, one of them via a KVM. this setup had been working for a while but somehow when I rebooted my PC this time, I only get this infamous black screen death symptom, it is only after I powered off one of the monitor that I figured out that's the cause...

count string Occurrences in a column and stuff string by number of space stored in another column

select len(YourCol)-len(replace(YourCol,'1','')),space(col2) + col3

JavaScript error: SCRIPT16389: Unspecified error.

we had an issue with running our enterprise web app (e4se) under IE8 and IE9, it gives error message "SCRIPT16389: Unspecified error", apparently this is not quite helpful but it did give me the line of the code that caused the panic.

here is the original code:

var oOption;
oOption = document.createElement("OPTION");
oOption.text = descValue;
oOption.value = codeValue;
sel.add(oOption); //this is where the error occurs

after refer to one of Microsoft's technical article on its Javascript implementation, I changed the above code to:

sel.options.add(oOption);
oOption.innerHTML = descValue;
oOption.value = codeValue;

the mentioned MS article is listed below:

very inspiring article...however in my case, if I get it of xmldocument all together (actually it is DataTable.select inside the xmldatadocument), the overall time it takes to finish project revaluation decreased from 30min to 12min!
