Yeah I forgot about the pause while I boil the kettle, make a cuppa, answer the phone then unpause to keep going. With ATC guarantee the moment you hand over to the autopilot they will call you and when you cannot respond. This invariably happened when I would be mid flight across the Pacific and come back to find the ATC window open and a lot of dialogue finishing with flight plan cancelled however flight was proceeding merrily so I leave it that and if I want reactivate the plan before top of descent, only trouble is the GPS can never reload the plan and pick up where you are in terms of the plan and always insists on giving your readings from the start of the plan and that is a real pain if you have the nav following GPS.

Think I will keep to flight following as I do now, too much trouble to do the other stuff.
