I hope someone can help. I have Acrobat 9 and some of the people I collaborate with have Acrobat 7. We share PDFs of articles from medical journals and need to annotate them (underlining text, drawing boxes, etc). Sometimes I will receive a PDF from a coworker that appears as a PDF/A when I open it. In such cases, most of the Commenting tools are grayed out. However, it turns out that my coworkers with Acrobat 7 don't have this problem--it's not a PDF/A for them and they can mark it up just fine.
Is there any way I can turn off the PDF/A mode? I've browsed through the menus and toolbars trying anything that might work and I am officially stumped. I'm pretty much a novice with Acrobat--I only use a few features--so please go easy on me when you try to explain.
Thank you so much for any help you can give.
