Occasionally mpgp will need to inform you about something, or need to ask you a question:
All of the announcements and questions presented by mpgp are set to timeout to default answers after some time. This is to avoid mpgp from become blocked if you are away from your computer for a long time. A dialog will show a countdown clock on the left, along with the default answer that will be assumed if you do not acknowledge the dialog. You can click the Wait button to stop the countdown timer. Note that all default assumptions are set to maximum safety - basically all requests will by default timeout and reject the incoming message if you do not respond to it.
