Overlay / Z-index and SEF issue.

Hello all, I searched the forums but can't seem to find a response to this so here goes.

I am using Joomla 1.7 template that uses T3 framework with MegaMenu navigation. I love the YJ Pop Login and is exactly what I need. At the moment I have gotten it to work with the exception of two issues as described below.

1. The YJ Pop Login seems to display above everything but the MegaMenu. By default the z-index for the login and registration popups in YJ Pop Login are set to 1000000 which should in theory display above all other content. The z-index for the Mega Menu is 11. Since the user can still scroll the page when the popup is active I need the popup to display on top of everything including the MegaMenu.

2. It seems that this module is not compatible with SEF. When I have SEF enabled in Joomla Settings the module doesn't work with content pages. Meaning it will work and log in and out of any page with the exception of article pages that have sef friendly url's. It throws one of two errors.

a.404-Article Not Found

b. Invalid Token

I would love it very much if you could assist me in getting these issues resolved. Thanks in advanced.
