It’s Shahinur again with another blog that I hope you find informative…
I was working on an issue lately where window.close() no longer seemed to close a window. This started happening after installing the October 08 IE Cumulative update MS08-058 (KB956390).
This was the code being used to close the window:
<DIV class=body align=right>Closing</DIV></BODY></HTML>
window.setTimeout("FinalCode()", 2000); //after 2 sec call the success() function to close the window
<DIV class=body align=right> Closing </DIV>
