Hi Graham,
I guess it is the QuickAFL that causes the unexpected behavior - adding that
seems to have cleared up some of the problems I was having but not all. I
have a couple of more specific questions regarding this and also the
different param functions which I think would probably require knowledge of
AB's internal workings, so I will drop a note to support. Thanks again for
your help!
Steve
