This looks like it is probably a CSS conflict with positioning of the modal popup. The newer versions of SCLogin rely on the Joomla modal code more than older versions of SCLogin, so we need to see how it's working with your template. Can you provide a URL where I can see the behavior in action and recommend a fix?
It works. I have created a custom sclogin theme, and a template override, as suggested in your article, so that when I update sclogin module, I won't have any issues, again.
Thanks
