WampServer

so, i upgraded from 1.7.2 to 1.7.3 and a ton of things just broke.

first of all i had no idea it would completely overwrite my httpd-vhosts.conf file which was annoying as hell. so i lost all of my virtualhosts that were working just fine before 'upgrading'.

so now i dont exactly remember how i had each virtualhost before. right now im trying things like:

<VirtualHost *:80>
ServerAdmin webmaster@localhost
DocumentRoot d:/wamp/www/drupal.dev/
ServerName drupal.dev
ServerAlias www.drupal.dev *.drupal.dev
</VirtualHost>

so drupal.dev works fine. but www.drupal.dev doesn't (instead tries to find it online). whats going on?? i have not changed my etc/hosts file (it still has all of my normal virtualhosts ie. drupal.dev, textpattern.dev, etc etc etc)

shouldn't the ServerAlias be picking up the www and *???
