Buttons and interactivity not working. I'm working on a MAC, latest MacOS, latest versions of all things Adobe. On export of my document to PDF, hover states no longer show for buttons, there's a huge lag on the response from buttons, and I'm also having a bizarre issue with clicks of buttons creating a box the shape of the button that is a preview of the page its supposed to jump to. All of this worked fine for me until a few weeks ago and all of a sudden, it no longer functions. Can anybody suggest ways to troubleshoot and find a fix?
