Pinpointing why changes are occurring in Normal template

[Larry]

I open Word, do various things, and then when I close Word, I get prompt
saying that changes have been made to Normal. I don't know what those
changes can be.

Is there a macro that would tell me the moment that a change has taken
place in Normal, so that I could pin point what the change is? I
suppose it's one of my macros might change some setting. But I want to
pinpoint the cause of the change.

Thanks,
Larry
