Windows pgpass Problems..

I have been stuggling all day with the pgpass ability on 8.0 Postgres - on Windows 2000.   I have been to the
documentation:<http://www.postgresql.org/docs/8.0/interactive/libpq-pgpass.html>After reading many threads on similar
problems,I just cannot seem to get a batch file to recognize that pgpass is there.   I have dropped it into the
Applicationdata directory postgresql\pgpass.conf of 'Administrator', (My windows username), 'postgres', 'All Users',
etc,etc.    The contents I have tried for the pgpass file areeach of the combinations of: 

localhost:5432:<mydbname>:<dbusername>:<the password>
127.0.0.1:5432:<mydbname>:<dbusername>:<the password>
localhost:*:<mydbname>:<dbusername>:<the password>
127.0.0.1:*:<mydbname>:<dbusername>:<the password>
..and many others

<dbusername> has been postgres and other test superuser accounts.   Nothing seems to work.  I have restarted postgres,
restartedwindows, and it simply wont take..
