Hi. Well, the memory sits at about 42% throughout. When I hit the search function, the first time, the CPU pops up to 100% for about one second, then during the time period before the results are displayed, the CPU runs at between 27% and 40%, dropping back to 3-5% when the results are displayed. The other screens report nominal activity.
As to the results of the tool that Kevin suggested, I downloaded it, tried to follow the instructions about three times, but without success. Clearly I was not following the procedure correctly, but pretty much abandoned that idea and did not pursue that aspect further because I have already taken up considerable air time with no readily-apparent solution.
And that's my report..... Clearly, nobody else in the forum is having such a problem.
