Files is listed despite use of: Options -Indexes WHY?

Files is listed despite use of: Options -Indexes WHY?

I have two relevant dirs in my webservers root

root/scripts

root/test

Then I have set up a virtualHost like the one at end of post:

I'm using
Options -indexes

Which work for all directories on
local.test.com

EXCEPT for the admin folder which still lists all files in that directory
(which is actually the files within: root/scripts)
if I do not put in a index.php that is.

Is there a way for me to prevent the files from beeing listed when entering:

local.test.com/admin

<VirtualHost *:80>
DocumentRoot c:/www/htdocs/test
ServerName local.test.com

Alias /admin c:/www/htdocs/scripts/

<directory "c:/www/htdocs/test">
Options -indexes
</directory>

</VirtualHost>
