Hi Lance,


   Please look at the attached file, and help me to get it
to work, please!  You could come over, or I could visit you.
   I am running under Red Hat Linux Fedora Core 1.
   Do you want to try Knoppix 3.4 on live CD, and KStars
1.0, which I told you I have when I last returned your
Java book?  Can you now burn a copy for yourself, please?



                       Thanks,


                       Joseph Roy D. North
