Last night's update was a definite case of "The cure is (!) worse than the illness."
I took a short nap about 9:00 pm and was asleep until 10:00 pm, when I woke I found that I could not get to my desktop; after closing from the off switch-I didn't have access to the shut down mode-I reset and was told the system needed repairing.
The repair took another 20 minutes to initiate and even then I had to restart my laptop, so after two repairs and a system restore I was able to get on line; an hour and a half after logging on :(
I found the problem recurred this morning and looked at the diagnosis, it was then I discovered I had to restore "lappy" back two days-hopefully, all will be well now.
