Tom and Philippe, about the 'flipped Mars' problem: you should get
this file:

http://www.projectpluto.com/planets.zip

which has corrected maps for Mars, among other planetary data. The
bug in question was one of the first ever detected in Guide 7, and is
described at

Jost, I don't know for sure why you're seeing that bug. But are
you, perhaps, using the debug version of LUNAR.DLL? I haven't updated
that for a while, because none of the functions in it had changed for
some time. However, it occurs to me that in the current version, there
_are_ changes, and that might cause trouble. I've therefore updated
the file; reasons for using it and a link to downloading it are at
