That's often a sign of corruption.  You should bakcup the mdb and then run
'compact and repair'.

If your users are all using the same copy of the database on the server, you
should split the database.  Put the backend (tables/relationships) mdb on
the server, and give each user a copy of the frontend (all other objects)
mdb on their workstation.  The frontend would contain links to the tables in
the backend.
