Although this not a strict vba question, some knowledge of the object model
could be of help, I think.

My question:
In some cases (but certainly not all!) after opening a document and
immediately closing it again or closing it after modification (either saving
these modifications or not), it happens that I'm prompted if I want to save
modifications in the attached template.
As far as I know no modifications have been made though. Nevertheless
probably some property of some object has been changed upon opening.
What could this be? How can I identify this? And most important: how can I
avoid this??

Thanks for any help!
Peter

(I've been thinking of something like styles which differ between the
document and the template; or updating a property like 'date last opened' or
so...)
