No problem I use forums lots to resole my issues. This is still quirkey when the user enters the wrong username/password it refreshes to double logins. But at least it displays only one at first.

Upon further testing I do believe that an article must be placed on the login screen or the loging will display double. When ever the front page article was unpublished it would display a double login once again. Something else to try if someone has this simular problem.
Cannot just have the login displayed by its self.
