This wizard destributes to each of the indicated groups BEFORE I hit the finish button! This is a majore issue, in my experience nothing should occur until the actual finish button is clicked.
I had a reason where I was told to wait on something at the last second before I hit finish, I hit cancle, and without warning I found out a couple hours later that it had sent out the upgrade packages to those groups. ( 80 groups so it took about an hour for me to remove them all ).
Thanks
