Right click, the icons at the top of the box for page rotate and crop result in an error message "Acrobat has encountered a problem. Some features may not work as expected." Others also result in this error message, it is VERY common. Accepting this via "OK" button causes a blank pop-up window to appear. To what point? It's blank!

These are silly errors that should have been sorted before this was released (and no one has bothered to fix). Users are being used as guinea pigs! If it's a beta release than users should have been told. Reality is it's rubbish. Full of bugs and inadequacies - just look at the huge number of feedback comments!
