Hi Pete,

When you say "reload"... do you mean "reinstalled the
program, then copied your horizon.dat file back in"?

Is the rest of the horizon showing up properly? If not,
take a look in Display... Background, to see if "Show Horizon"
is checked.

If that doesn't answer the question, it would probably be
a good idea to e-mail me your 'horizon.dat' file; I might
see an answer in that file.
