I have an action that crops all pages in a document to the same size. I run it on pages that come out of InDesign to get rid of crop marks that our printer uses (pages w/ crop marks are printed and bound into a magazine, pages w/o get posted on our web site). I've used this action for years without issue (specifically, it crops, optimizes, saves, and closes the doc). Recently, running this action has caused random letters to drop out of words in the PDF (for example, one of the "l"s in "specifically", so I end up with "specifical y" instead. Any ideas what happened and how to fix it? It takes 3x as long to accomplish the same thing without using the action.
Please tell the OS you work on along with the Acrobat version.

Quick update, this appears to be related to the optimizing part of the action. I am still experimenting but I have that narrowed down.
