Small correction, I just checked and I have v1.05.
On Gemini's website they list all the previous bugfixes (
http://www.docgoerlich.de/Gemini.html), PAC for southern hemisphere was fixed back in version L3 v1.05, March 2004 ! However I wonder if he accidentally reintroduced the bug, or if I'm doing something wrong. I was hoping someone could corroborate my story before I went to complain to the manufacturer.
