Hello all,

I've fixed the issue mentioned by Enrico Pettarin : when you attempt
to import orbital elements generated by Find_Orb, it should work correctly
now. This should be true whether you generate "standard" or "alternative"
format elements... essentially, just create orbital elements and let Guide
figure them out. The update is, as usual, at

http://www.projectpluto.com/new.htm

Also, I am pretty sure that I've fixed the issue Christian Ambros
mentioned. He sent me his overlay files, and they all looked good.
However, I've gone through my overlay code and found and fixed some
very ugly bugs, including one that I'm reasonably certain caused the
crashes Christian reported... and which really should have caused crashes
elsewhere. So I highly recommend getting this update.

In the process of doing all this, I've also added some more error
checking. In many places in Guide, I had set things up to give a
reasonably informative error message; instead of just crashing, the
program is supposed to say something such as

'marks.nam' not opened: Permission denied

However, it turned out that the overlay code wasn't using that
error checking. It now does. So if there are further bugs out there,
they should at least be easier to find and fix now.
