Locking text boxes within a pdf
Hi there. I need to lock multiple text boxes within a pdf document. The document has over 600 pages and there are 4405 text boxes. I know that in theory I can lock all by going to Tools/Comments/Open then selecting all the comments, right click and tick Locked but the document is so big that it crashes when I try to do this. Even scrolling down the list of comments to highlight prior to right clicking them all takes ages and then results in a Not Responding message. Any tips for a pain-free way to do this, please?
