file date/contents fail to update on copy

[Stephen Russell]

I've found some win95/98 machines will fail to update the local file
date/time stamp and contents of files which had been modified on the
server using a server text editing tool.

The engineer will edit one or more files under Unix (solaris), use the
win95/98 client in drag/drop or explicit copy/paste copy mode from a
samba share to the local hard disk and the system will not update the
existing client files to the newer date/contents as modified on the
server.

We're running samba 1.9.18p10 on a sparc20.

any clues here (I'm the pc guy, not the unix guy).
