WebDav problem - permissions?

Hi. I've installed the WebDav module and I can load the directory with
windows explorer at a remote site with no problems. I can navigate the
directory just fine. But when I try to open the files, there's no "open"
command. Double clicking does nothing. Local pdfs or pdfs on networked
machines work fine.

Also, it doesn't allow me to delete, create a new folder, move, or rename.
This smacks of a permissions problem, but that still doesn't explain the
difficulty opening files, does it?

Anyway, running FreeBSD 5.3. Here's the relevant part of httpd.conf:

<Directory "/usr/local/www/data/docs">
DAV On
AuthType Basic
AuthName "Password required!"
AuthUserFile /usr/local/etc/apache/passwd/passwords
Require valid-user
</Directory>

By the way, the directory /usr/local/www/data/docs is a symbolic link to
/files/docs. But I didn't think it would be a symbolic links problem
because I'm able to navigate the directories with no trouble.

Also, the auth stuff is ok for typical web browsing. That is, I can
navigate and open the files in those directories in a web browser after
entering the same user name and password. It's just the WebDav that's not
allowing me.
