I am on Windows 8.1 and using InDesign CC 2015. After approx. 15 min of inactivity I get a message saying I lost network connection and Windows is shutting down the program. Once shuts down I re-open it and all is well until the next time I walk a way. This only happens with InDesign CC 2015. Did not happen with 2014 and does not happen with another of my software.
