I'm trying to handle compatability issues with older versions of Office.
From
what I have gathered through googleing and this forum is to build to the
lowest denominator. Thats fine with me, but... how do I rerference older
libraries on a new machine? Also, if I reference rev9 office libraries,
will
this cause any probs with the newer machines?

Thanks in advance!
