PDF’s closing in about 10 seconds

[Keitepeheakoe]

Can anyone explain why PDFs are now closing in a few seconds rather than remaining open! It’s doing my head in!

Are you using Acrobat Reader? If so check if there is an update available. I had this when my work laptop was upgraded. Updating Reader sorted it.

No updates, no

Which application are you using to read PDFs? Acrobat Reader or something else?
