Hi Anthony,

There have been some rather nasty issues affecting comets lately. I expect
to post updated software that will avoid the issues... but in the meantime,
I recommend that you download this file:

http://www.projectpluto.com/comets.zip (about 52 KBytes)

and unZIP it in your Guide folder. (This works for Guides 7, 8, and 9,
by the way.)

This will both fix the issues with downloads, _and_ give you comets that
are not "currently visible" (the MPC updates aren't very complete in this
regard), _and_ fix some problems caused by comets that have received a
permanent designation; you can otherwise get situations where you see a
comet twice, once with a provisional designation and once with a permanent
designation.
