1. Comment markups randomly disappear from the screen, sometimes when zooming in and out, sometimes when scrolling. Sometimes they all disappear, sometimes just part of a page. Zooming or scrolling does not fix the problem. They will not draw correctly until I hide Acrobat, then making it the active application again, sometimes I have to quit the application and restart to solve the problem.

I need to use a split screen, half InDesign, half Acrobat, when I'm running corrections. That does not leave real estate for the giant comment sidebar in Acrobat, so I need to be able to see ALL markups on the page in the PDF. I have repeatedly missed edits on a spread because they randomly aren't visible.
