It could be that you are using an old version of IE and independantly
redicovered this vulnerability but I sincerely doubt it, especially since
you refer to the issue as being in a javascript function, when it was infact
the possibilty to create an activex objects that was the issue ( writeline
is a method of the filesystem activex object)
