Setting Profile/ForceSignUp site setting to True locks the user to profile page?

Hey all,

Have a bit of a problem. Did some looking around the forums and I want to force new users to go through the profile page to update all their details etc. before they are able to access the components of the system. I've made a custom profile template and changed my profile page to use that, and that all works fine.
However when I changed the site setting "Profile/ForceSignUp" to True it seems to lock you on the profile page. Not sure if this is because I've done a custom template / form on the profile entity, however I press submit on the form and it doesn't allow me to access any other contents on the portal.
Any help on this would be appreciated :)

Kind Regards
Josh
