Hi,
I am on NCM 7.1.1 and I noticed the same thing. However, I think if you are looking at the "Config Summary" page and clicking on the "Change Report", the top of the change report should provide the last a time stamp on when last a report was changed and by who. Most times when I see the lines that seem to have changed it shows that its just a spacing thing and the shows the corresponding added line on the other side. Note in the 2 examples, on the second one there was a power outage so technically there wasn't a configuration change but now in the config it no longer had the last person that made a change, it just states there have been no changes since last restart.

You may just need to explain to them that its the way the NCM downloads the configs.
