Fun with Adobe update

If you let Acrobat or Acrobat Reader update itself, you may have to check your preferences. When I let Acrobat Reader apply the latest update, it changed my JavaScript preference from OFF back to ON. If your preference is to leave it OFF, then verify this preference every time you update Acrobat or Acrobat Reader.
Very few PDF documents require JavaScript. Leaving JavaScript OFF helps to protect you from JavaScript exploits -- when a document does need it, Acrobat will ask you whether you want to turn it back on and YOU can decide for yourself whether you want to turn it back on, rather than letting the document decide. But ... if you turn it on, remember that it is not temporary - you will have to turn it back OFF manually.
