Thank you for the fast response, but it still does'nt work :-/
is there another option to rotate pages – eg. manual like in Photoshop?
just tried this with InDesign CC 2017 on Mac OSX 10.10.5.
No problem to rotate the pages view.
funny... just tried it with another document and it works !!!!
...maybe it was just that one file...
regards and thank you!
