Actually, this description does not quite seem to explain what I have
observed. Sometimes when there are lots of programs running in the
background on a slow computer, and my program is not too simple, I
find that I occasionally get a delayed response to a key even if I
hold it down. It might have something to do with the fact that I am
using the arrow keys on the numerical keypad, and it might also have
something to do with the fact that I often switch from one arrow key
to another quite rapidly. Am I observing the expected behavior, or is
there a problem?
