How to get more control about change and save of project settings

My issue is that when I open a project created with an older CVI Version e.g. created with CVI 7.1 and opened with CVI17/CVI12 that it automatically change some setting (do not have a clue which ones) and when I close the CVI IDE it automatically save the changes without asking "Do you want to save? Yes/No".
And the changement is indicated by an asterix * on the project name inside the project explorer of CVI.
