Hello, it took a while, but I think it's fixed in the new beta for version 0.7.10. I'll still need some time for testing, but currently it appears to be working fine. If you'd like to give it a try, you can find the source at https://spellbreaker.org/~chrender/fizmo/source-beta/fizmo-0.7.10-b3.tar.gz for download.
If everything works well I hope I can submit a new upstream version next week. Best regards, Christoph.
