Hi David,

Nope, you've caught a for-real bug here. You'll probably find that
the function does work when you've got the first Guide CD in the
CD-ROM drive.

Alternatively, you can download this file to your Guide directory:

http://www.projectpluto.com/filelist.dat

and go into "Extras... Install to Hard Drive." Turn something on
or off (doesn't matter what it is, as long as something changes;
if no items are changed, Guide figures it doesn't have to do anything.)
Then return to "Extras... Install to Hard Drive" and turn that
something back off or on.

All this will cause Guide to re-examine the list of installed files,
and this time, it'll pick up the Abell cluster data.
