Ahh yep, it's probably apache. The nginx config included in the repository rewrites all URLs to index.php to solve the problem you're having with the URL. I imagine I should add an .htaccess file so anyone running apache doesn't have to deal with this.

Also - regarding the changing templates and clearing the cache: if you use index_dev.php instead of index.php, it won't use the cache and you won't have to clear it every time :)
