Untrue. I pointed out the flaws last time this subject was discussed
on this mailing list. Was that just a few days ago, or was it last
week? I don't remember.

Lots of scripts will work "if certain conditions hold true". That's the
fundamental problem here. The script shown here is incredibly fragile,
and the author did not correct the flaws that I already pointed out
last time. It may "work" under certain conditions. How likely those
conditions are to be true, I have no way to know.

Yup, that was one of the three(?) proposals I made last time around,
none of which were followed. *shrug* Not much more I can do when
nobody listens to me.
