Hi Larry,

Yup, I see it, too... comets _and_ asteroids vanish if one
goes into the Inversion menu and sets "Chart Inverted". I've
fixed this. I'll probably post an interim release with this
fix included.

"...I am using the Feb 2005 version of Guide. I noticed it
did the same in the Oct 2004 version also." It's probably done
it for quite a while; the relevant chunk of code has been
present for a long time. I'm astounded that nobody mentioned
this.

Another opportunity for me to mention this: don't assume
that I "must already know" about a given bug. For example, I
usually don't have the program running in inverted mode, or
in a language other than English, or with the time zone set
to Local Mean Time. So things get by me. If you see a bug...
please let me know. It doesn't guarantee that I'll see that
bug and fix it immediately, but it makes it _much_ more likely!
