"it would be nice for other's to know how you resolved your issue."
Dear Mr. Mixx,
I entirely agree with you, I am sorry for not being able to answer, but I did not receive a notification that someone has replied!
Anyway, John was very kind to explain to me that this was likely caused by having the computer and the lamp connected to the same power bar. Following John's advice I connected the lamp elsewhere and the problem was solved. I never thought computers are so sensitive! But now I know that they don't like to be connected to the same power bar! They like to be left alone instead!
Thank you very much for the IBM Lotus screenshots
