Can you post a screenshot? Are you on Mac or Windows?
Thanks for replying, Pariah.
I'm Mac OS Sierra.
I was wondering if I could post a screen shot... I don't see where how to attach to the message though....
and here's what I get when I press the green button on the PDF header to open the document ( which I never had to do previously, it just automatically opened at 100% size, but not in maximized screen mode.
Also, Acrobat just crashed, coincidentally.
I checked my Creative Suite and looks like I have the most current version.
