[kde-edu]: Machholz wrong position on chart

[Jason Harris]

When you say the file is "from JPL", does that mean you used the "Get New 
Stuff" tool in KStars to install this file, or that you followed the 
instructions in README.ephemerides?

Can you send to me (kstars at 30doradus.org) the comets.dat file that's giving 
you trouble?

The warning messages are nothing to be concerned about.  I don't yet know why 
KStars is hanging for you.
