We recently have started having issues with users trying to open files
which
say they are open by another machine and are then opened read only.
This
isn't the case or this was hours ago. If the user then closes and then

re-opens the file almost instantly, it is fine and no longer says read
only.
So far have spotted this on Windows XP sp1 machines with Novell Client
4.83
sp1. We run NW5.1. Any ideas?
