How do we stop Adobe Reader from asking "Do you want to save changes to '*.pdf' before closing? Yes, No, Cancel

I think JavaScript is a section under Tools. There's an Edit All.

What version of Acrobat Pro do you have?

So, if it's even after saving, and if you reopen the SAVED file (not the same file from a web site, not the same file in an email!) then it isn't a faulty PDF. Maybe it's an embedded JavaScript doing it.

If you're not making any changes yourself to the file and it still happens then it might be because the files are corrupt and Reader fixes them when it opens them, so they could be displayed despite the corruption. Another option is that there's a script embedded in the file that is executed when the file is opened and makes changes to it (to a the value of a form field, for example), so the file is considered to be "changed" by the application.

Hi JT,

That's a precautionary warning which appears only when you make some changes in the document and then try to close the document without saving it.

and No, there's no such option to turn it off.
