Alex,
Take a look at "loopviewer.hqx", rather than "loopdloop.hqx" at the
same location. That is a simple viewer program for mulfold output.
The name of the RNA fold program at this site is "mulfold.hqx".
The archive site is ftp.bio.indiana.edu, and the directory for
these mac programs is molbio/mac/
