I have been using NIS for ages. I recently used it not more than a few days ago. Today, Nov 29, 2014, I decided I wanted to add a program to the program rules. I brought up the norton screen, clicked Settings on the main UI, then Network then Smart firewall then click on Program Rules (configure).
Before today whenever I clicked on "add" it would bring up a Windows Explorer interface so I can see folders/directories/drives on the left and the contents of those to the right just like Windows Explorer. Tonight when I did, I instead just got a simple interface that says "Browse for files or Folders" as the box name and then it says "Select a program" and it then just list a directory with the > next to it which of course when you click on it, it opens up the directory.
