This would happen if you are using the free trial version of Splashtop XDisplay. You can download and install the Splashtop XDisplay client and server for free, but it is not a "free app;" there is a ten-minute limitation. So, the free version can be used for connection sessions of only 10 minutes at a time, then it will automatically disconnect. You can still re-connect again every 10 minutes. To enjoy this app without having to re-connect every ten minutes, you can upgrade to the full, unlimited-use version.
