Hi,
The problem lies in the screen shot no. 3rd.
You have opened the same project in parallel. Just have a look what message is coming at the bottom. "Not all object were locked" and you yourself have marked it will yellow color. Please look that it is not only project currency, infact everything went in disabled mode including project definition and first level WBS too.
So, when you have changed the OPUJ settings from Display to Input. It must have worked fine for you if you have not opened the same project in another window. Please note that if it is working in case of hide and why does it not work for input ?
Solution:-
1. Close the project and make sure that it is not opened in any of yours landscape client.
2. Change the OPUJ settings from Display to Input (You have already done that as per your feedback)
2. Check the project and you are done.
I hope I am clear to you..!!
Regards,
Amit Rajoria.
