The jQuery library I am using for modal window does not show vertical scroll bar for full screen. I am trying to find a solution by either applying extra css for the window generated by the library or creating my own modal window(div). I read a little on both but with no success. I switched to connections feature. I just found the right code to use to check for user permissions; I need this to allow or deny access to this feature which is meant to be used by site admins.
