Thank you both.
Will try to note the details if it recurs but (touching wood) nothing , so far, today. I'm afraid that the 'geeky' stuff about ports etc passes me by, but the one thing I've learned from practical experience over the last fourteen or fifteen years with 'pooters' is .... don't allow ANY AUTOMATIC anything!!!!!
What I wish to do, and what some anonymous bunch of program writers wish to do, with my machine, may well be poles apart. At the end of the day, a full re-install solves most things and, using Windoze, it has, of necessity, become a regular ritual
