Wrong messages running on Windows

Hi! I've been using the PostgreSQL database in Windows since the Beta2-dev3, and it had a bug I didn't report. I've just downloaded the rc2, and uninstalled my previous version, and installed the newest one, and it still have the same bug.

When executing the command line functions psql, pg_dump, createuser, createdb, dropuser, dropdb, they output a message in the format:

could not find a "functionname" to execute

where functionname is the name of the function i'm using.

Hope you can help me with this "bug" (if it is), so PostgreSQL can continue improving.

Thanks a lot.

P.S.: I'm running Windows 2000 Professional with Service Pack 4, with all critical updates installed. My OS version is in Spanish (and most of my software too). My computer is an Intel Celeron 600 MHz, 256 MB RAM, 40 GB HDD (with 4 partitions, all in NTFS).
