Kitkat,
Years back my Kn6000 had that same problem, after 10 trips to N. Miami ,100 miles round trip it was not any better. I feel the technicians were at fault, I do not think they were trained to work on keyboards. Bottom line; they gave me, no cost a new Kn6500.

After the problem was over I learned that the problem was in the keyboard contacts. Bob�s post is right on the subject, his knowledge is good, �poor or erratic contacts of the key mechanism�.

PS, A spider in the keyboard?? I wonder how good of a player he was.
