Groucho--
You were right. I thought we could rule out fans, but that turned out 
to be the problem. She'd moved a small clip-on fan to the bookshelf 
above, but hadn't mentioned it to me, since it was plugged into another 
outlet. She was all set to take it to the repair place, but called them 
first, and they advised her to move it 4 ft. away. I thought you meant 
it might be the airflow from the fan, but they told her the motor was 
the problem. Whatever, I'm relieved.

And grateful for the speedy help from this list, too.
