Pretty good take on it Gregg. I recall once, back in the late '80's, on an old character generator that had a sticky key problem, so I flushed it all out, several years worth of grit mixed with hand creams of dubious ancestry, with wd-40. 3 days later it had lost 3 keys. I called the CG folks who practically fainted when I said I had used wd-40 to clean it. They said put the phone down, and run, don't walk to the dishwasher, put it in the top rack and run at least 3 cycles with the last using just a squirt of palmolive. Turned out that the $16/copy Cherry brand key switches were hall effect devices that were being poisoned by the wd-40's petroleum content. In the end I wound up replacing 7 of them. It was a pretty heavy duty keyboard, similar to the old IBM's that weighed about 5 lbs and could be used to smash a skull in a pinch. It had by then probably typed a million words or more. And it probably did another million by the time we retired it 10+ years later. Cheers, Gene -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
