I have fixed the 31DEC12 version and would not  count on 31DEC11 working 
as this option was intended to work.  I had to go back to 2009 versions 
to see the true intentions.  The addition of options to divide the IFs 
into halves, quarters, etc confused the confused way this option was 
handled previously.
