Login page not working with second theme


i’m trying to create a login-page that doesn’t use the default theme.
I created a second theme that i enable trough the ‘page theme’ module to show the user/login page.
while customizing this page i used the page.tpl.php, not a template.

The login form does work however if i use the default theme with a template page user-login.tpl.php.
But this is not what i want, because it calls up the header, footer, etc… of the default theme.

My problem starts here:
By using another theme for the user/login page it appears that the login form does not work here.
It doens’t even respond when you fill in the form.

Can anybody help me?
Much appreciated!

PS: I use drupal 7.
