Running NW 6.5 SP7

I have tried a few combinations of access rights and I am not able to keep a
user from dragging folders around by accident while still allowing them to
create, save and edit files in those directories.

Has anyone else had this problem? Is there a solution I am missing? Or is
it just a fact of life that too much power is often abused? It seems to
always happen when I am away for vacation or on a business trip, someone
drags a top level directory and drops it accidentally into another
directory.

Any hints on this?

Currently I have the following allowed (checked)

R W E C M F

None of them are Supervisors or Administrators (S / A)
