A late reply to an inquiry from Laren Dart: Guide does have a full-screen
mode, described at

http://www.projectpluto.com/update8.htm#full_screen

David, my apologies: I saw that the file 'abell.dat' wasn't copied
over, and thought I'd found the problem. Turns out that file isn't
actually used for anything, and the file that _is_ relevant ('richclus.dat')
_does_ get copied over. At this point, I dunno why the objects
aren't getting found. I told it to go to objects 1, 12, and a few others,
all with success. Perhaps you got failures with different numbers?
