Hugh and Bernard were correct when they were suspecting
the battery. My "triumph" (my last message) was premature.
Knowing how to correct the pincushion is one thing but making
sure it does not reappear after a while is another. Since my
computer is 4 years old I decided to replace the battery ($21,
including tax and labor) and see the result. So far all is good
(no pincushion) but I should wait couple of hours to be sure.
Clock batteries are supposed to last 3 to 5 years, they said.
