Popup Login plugin suggestion

Hi everyone

Can anyone suggest a login popup plugin?

The idea is to have “login/register” in my header menu. When clicked on a window pops up a Login or registration field. When logged in the “login/register” should change to “logout”.

I have used plugin CM Registration, that does exactly that but, there is a delay when clicking on the button and the plugin doesn’t allow the system to send out a welcome email. After those faults I decided not to use it anymore.

Can anyone suggest any plugins that can do this?
Thank you
