Question: Why is it that when I open an app - say the Mail app or the Store App and close it - either by clicking on the x at the top right corner or by dragging it down in the traditional way - am I thrown back into the desktop even though I opened the app from the Start screen?
Desktop Machine or Surface 2? If it is your desktop it is by design, if it is your Surface 2 it may have synched that setting from your desktop assuming it is now running the Update as well...
