On my copy of ZETLite, which by the way is far superior to every other astrology program I have used, the alchemical element symbols are not correct, in specific, the water and earth symbols are exchanged. Is this a common problem?

There several variants of element symbols depicting. You right, in the West more often used the variant you talk about, but I prefer the variant in which the moist elements depict with line, and dry - without it. But you always can replace the glyphs of the Water and Earth by ZET's font editor (Alt+F2 key, symbols #20 and #22).


The Ptolemy's planetary Terms sequence for Gemini should be "Mercury 1-7, Jupiter 8-14, Venus 15-21, Saturn 22-25, Mars 26-30", but in ZET gives other.

What you mean is Lilly's variant. See "Christian Astrology" by W.Lilly. But according Ptolemy's Tetrabiblos the planetary Terms sequence for Gemini are some other: "Mercury 1-7, Jupiter 8-13, Venus 14-20, Mars 21-26, Saturn 27-30". See: Ptolemy. Tetrabiblos / Edited and translated by F.E.Robbins. - Cambridge, Massacusetts; London: Harvard University Press, 2001. You can choose preferred variant, see Chart Settings, Style tab, "Terms of the planets" checkbox.

Regarding the fixed stars, I am confused. The locations are in the sidereal constellations, for instance Algol at 26 Taurus.

Press "Setup" button, select "General setup" and find "Precession" box. Default setting is: "Calculate when set date". It means that a precession for stars calculates only when you press "Execute" button in "Birth Data" window. When you change a time dynamically - it does not calculated. Try other settings. And read manual about it.

Why ZET have a two second of Sidereal Time difference from Swiss Ephemerides (Astrodienst)?

Here is a part of my dialog (17/08/01) with Dieter Koch, autor of Astrodienst:
>Hello Dieter,
>I have one question else about Swiss Ephemerides.

>1) SE               66.0271 sec
>2) Moshier (aa54g)  63.8296 sec
>3) ftp://maia.usno.navy.mil/ser7/deltat.data
>                    63.8285 sec
>Why SE differ?
>Befor 1997 results are same:
>1)   61.6285 sec
>2)   61.6289 sec
>3)   61.6287
Sdrastwi Anatoly
Yes, it seems that the Swisseph values are outdated, because we still use extrapolated values taken from the Astronomical Almanach 1997. And the values from ftp://maia.usno.navy.mil/ser7/deltat.data are correct. Unfortunately, delta t cannot be known exactly ahead, but has to be calculated every year from new measurements. Thank you for the clue! We ought to adjust delta t every year, but we have forgotten it.
