mod_auth BASIC kills ftp access?

not sure what is going on here - i run a server on my desktop to test
files / config settings prior to posting them to my departmental server.
i also have an FTP server running to allow me to be able to access my
desktop from home when uploading and testing files.

yesterday i implemented mod_auth basic password protection on two
directories i don't want people poking around in - but now i can't get
access to the server using FTP unless apache is shut down. i can
connect, but i can't get a directory listing. any ideas?

test server is running apache 2.0.46, win98, filezilla FTP server. i've
had apache up and running for 2+ years now with no major problems -
can't understand how http server would conflict with an FTP request.
apache is bound to port 80 only , FTP uses 21 - nothing strange.

directory setup from my httpd.conf file:

<Directory "C:/path/to/protected/dir/">
Options Indexes MultiViews
AllowOverride None
Order allow,deny
Allow from all
AuthType Basic
AuthName "protected dir"
AuthUserFile "C:/path/to/passwd/file"
Require valid-user
</Directory>

any help would be appreciated.

oops - just tried shutting down mod_auth. didn't help. it's the httpd
server itself, not the module...

apparently running apache 2.0.46 interferes with my FTP server - i
upgraded from 2.0.40; any idea why 2.0.40 wouldn't bother FTP, but
2.0.46 results in denial of directory listings? my FTP server runs fine
if i kill apache (see original post)
