   Dunno if this is your problem, but when I was using a MacPlus, I found I
   could run MACL exactly once per boot.  Version 1.3.2 would work under
   Multifinder; 1.2.2 wouldn't.  Note that this is purely empirical; I
   never tried to figure out why any of these behaviors obtained.

This is almost definitely the sign of infection by a virus.
