This is a problem we discovered late in the release cycle, and it is
documented in the Release Notes under "Miscellaneous". It means that the
summary files "__sum4.txt" and "__sum4i.txt" are out of synch. (The latter
was added in Release 3 to improve performance during startup.) The most
frequent cause of this problem is installing Release 3 more than once with
the same working database (_data) directory.

The solution is to do the following:

1. Exit S-PLUS.
2. Delete the files called "__sum4i.txt", "__sum4.txt", and "__sum4.tx_"
from your working database (_data) directory.
3. Restart S-PLUS. (This will re-create the files properly.)

The problem should not recur unless you again re-install in the same
