Login Modal Doesn't Load

Joomla 1.7.1
PM 2.1

When clicking the template login button at the right of the main menu, it redirects to a system login page instead of loading the form in the modal window. I've looked and cannot find any settings which could affect this.

Please advise on what I may need to do in order to get this to function properly.

Thanks.

Disregard. Had mod_login properly published to "login" position, but access settings had gotten changed which prevented the modal load.
