I am a long time NIS user and this issue is not secific to my latest version. If I open the NIS main screen and select Live Update it may say that it last checked 2 minutes ago. If I tell it to run live update, it may find 2 or 3 updates and install them, some of which could have been labeled as critical. So ...... if there were updates available and it had just run 2 minutes ago ..... why didnt it install them?
