Thanks Kevin, I was doing it right except that I was positioning the
master object which was being cloned instead of the clone itself! A
simple bug in my code led me astray! My geometry was correct and I'd
already thought to zero both the vScroll and hScroll before making
new objects in the group.
Thanks again for the quick response.
