This symptom arises the suspicion that something is wrong with the ksh
environment (logging out & back resets it).  Check if you didn't manage to
create an alias or a function named 'su' - i.e. next time this happens, do
'type su' and check if it still points to /bin/su.  (Coming to think of
it, this may be a viral password-catcher planted in your home dir!)
