I have an issue with this as well. Is there any way to find out which "securables" have been secured? I have thousands of tables, of which half have been granted the "select" permission. So, I don't want to have to add 1000 tables, and scroll through them to find the 500 that have permissions. Is there something somewhere that will allow me to view only the objects that have any type of permissions against them. If not, this seems like a major bug in Management Studio.
