Any time I open a PDF and then merely print the document, I cannot simply close the PDF once printed. I get a pop-up box asking if I want to 'save changes to xxxxx.pdf before closing.' This is quite annoying when I have multiple documents open and have to click No for each PDF I have just printed.

This pop-up is a relatively new 'feature' so it must have been activated by a recent update.

I aks that you please fix this issue.
