    I am not sure if this will answer you question  ..but we encountered a
similar problems when we developed our "online" ordering and delivery system
for our DNA seq. facility.
    The work around was ...instead using http URL to download the file we
used ftp URL
i.e ftp://dna.arizona.edu/pub/file.cro instead of
    We have users opening these files on mac using Editview and PC users
using chromas/abiview ..unix folks using trev/gcg etc.
