  Thats not a good assumption.  The person doing bugs may be busy, may have 
  not checked the mail yet, or may be trying to reproduce it.

  The lock on my hard drive wont let me update or append a file (existing or
  not) using standard DOS commands.

  See above.

  I tried this and your right! Zoo does change the file (as indicated by the
  date stamp). But I havent been able to get anyting else (besides zoo) to
  reproduce this.

  Darn this shoots my theory of keeping the Euro-Virus out of my C: directory.
