Thanks for the info.
But if it is an intentional change, based on my experience, some more needs to be done to complete that process. If nothing is done, Microsoft will have to include some type of disclaimer stating the process and the necessity to shutdown the app, using the mentioned process, prior to restarting or shutting down.
Since a very small portion of the Windows 8.1 users are in these forums, they will not get the word as to the procedural change. In the attachment, Sudoku has been closed without the mentioned process, while I am attempting to set my display to span multiple monitors.
The program needs to be closed type message will also appear during restarts and shutdowns.
