I own a Lumia 920 WP8. All of a sudden the Windows Phone application in Windows 8 has stopped starting up automatically when the phone is connected via the USB cable. I have checked the setting in control panel "auto play" and it is set to "move things between your phone and pc (Windows Phone)" as before, and in the settings/Preferences for the Windows Phone application, Automatic Import is selected. I have uninstalled and reinstalled the application to see if that helps but it has made no difference.
I have tried changing the setting to "ask me" in control panel and then back to "move things" but that makes no difference.
