If I double-click on a comment it rises in the height (because of the post-button). Sometimes it rises also without double clicking, just on one click! If I click on the next comment the comment before shrinks and the current comment rises. So the complete list AND the current comment slips up. So if I have al list of 1000 comments and copy every comment-text to paste it in InDesign, my eyes and my brain gets tired of the constant comment-slipping. It's also hard to orientate if I switch between InDesign and Acrobat. Especially if the comment panels just shows half of the amount of comments compare to Acrobat X. That means I have to scroll additional much more than before. And after a scroll I have to orientate again.

Please make the single comment the same size no matter if the comment is closed or opened (to post a comment or copy the comment-text).
