Just wondering, would the hiding routine go faster if I were to select a
range of columns to hide, rather than just one column at a time? That is
what I was originally trying to do and couldn't get it right. If you don't
think so, use what you gave me.

Another issue:
Do you know if I have cells within the column protected, I can't seem to
hide the column. Do you know how to allow protected cells to be hidden and
still be protected?
