I use acrobat pro to edit powerpoint presentations that have been turned into PDFs. In some documents, certain pages won't let me select images using the edit text & images function ( normally if you hover over, a blue outline appears, indicating something you can select but nothing happens one these slides), and I can select the add text tool and create a text box, but whatever I type in it doesn't show up. I've tried switching back and forth between the selection tool and the hand tool, but that doesn't make a difference.
I have tried adding sticky notes on these pages, which seems to work, but often makes the program crash before I can save what I wrote.
Thanks in advance for any help.
