Disastrous update
I know it's been mentioned elsewhere but the latest version of Adobe Acrobat Pro is terrible!
I've been struggling with the new interface (I need the scroll bars to show permanently on comments which doesn't seem possible now) but the incompatibility with Enfocus Pitstop was the final straw and I had to get rid of it to get any work done.
I've reverted back to the previous version on my Mac using Time Machine. So much better!
Disable 'Automatically install updates' ASAP if you haven't updated or can revert to a previous version - this current one is a disaster for professional use!
