Wow! :-) Thank you! Now is it O.K. dialog is not apearing!
Thank you ones more.
Happy to help
THANK YOU - this was driving me nuts. unchecking the "Enable assistive technology support" stopped that dialog box from popping up for me. i had read several other posts advising to change more settings & doing stuff i didn't feel comfortable in doing. glad i found this thread before trying them. i think i was mostly uncomfortable because i didn't understand what the dialog was for. now that i get it's for screen readers, that i don't have nor need to use, i'm okay with disabling the preference/feature.
the thing that's still boggling my mind is... i exported 2 artboards from 1 Illustrator document with the same PDF settings & only 1 of them causes this dialog box to come up. weird. am open to hearing theories on that if ya got 'em.
