Well bugger me. I thought I'd found the homepage at
http://strohmayer.org/sfs/ but that is now looking old if you have a newer version

Odd that the latest I could find on Aminet matches the one in the link I've stated.
Something strange going on anyway. The version numbers on the site I listed don't correlate with the version numbers I found on your site..it's almost like they're two different softwares.
