user exists but mylog says it does not???

Greetings,

PostgreSQL 7.4 on RedHat 9.

I don't get this. I can use 'psql -U maxware -W' from the command line to
access the database. I've set up the same username and password in the
system DSN. However, the application using the DSN gives the following
user not exists error in mylog. How so?

By the way, the application is running on the IIS on a Windows 2000.

Also, I apologize for the poor format of the following extracted log
information. Right now, both my mylog and psqlodbc files are not easy to
read due to no line breaks. What I can do to get it better formated?
