The solution is to make sure you are using the latest file utils and not 4.0
or earlier. From memory last year, as such there may be some mistakes in my
response below:-

When working on some re-builds last year of the 2.04 there were a series of
problems found with fileutils 4.0 and the 2.04 code, one of them was this
and another was a problem with rm where it could wipe the hard drive under
some very specific conditions (I think it may have been very deep directory
tree or something like that).

I personally seen the problem above with file utils 4.0 and the 2.04 code
from sometiem last year (50% chance arround May-July time frame). 

The fix required a modifiaction to the fileutils and I think it was done as
an update to the fileutils 4.1 as it was being released or had just been
released at about the same time.

Hope this helps.

IMHO:- If it does exist in the latest versions on Win 98 then try the
filutils built with the 2.04 alpha release. In either case under 2K (or XP)
I would use the fileutils built with 2.04 as there are some changes to the
file IO that have not made it into the 2.03 refresh and the 2.04 is very
stable.
