The SCLogin module simply connects to the standard Joomla user component. The SCLogin module isn't a component by itself. When the user tries to login, we simply redirect them to the Joomla user component to process that login and, when it fails, Joomla redirects them to the standard Joomla login page. We don't have any control over that.
In general, all we can recommend is making sure the Joomla login area looks how you want it to look as many extensions will automatically redirect the user there, either when they try to access restricted content or like in this case with the SCLogin.
I hope this helps clarify the issue and am glad you are happy with the module otherwise.
