This links goes to a specific post in the thread.  Don't scroll or you
will have to dig.  The one to look far if it messes up is the post by
NeddySeagoon.

According to one page I found, this happened several years ago so no
idea how anyone missed it this long.  It was discussed on this very list
but my archives don't go back that far.  I figure if I don't run into a
problem in a year or so, I missed it which is a odd thing of itself
since I usually find every problem there is.  ;-)
