And, David1o1, you never recovered from your ignorance and stupidity... sadly. I'm guessing it showed up again when you used the zapper.
It requires knowing how, which, if in fact you bought one, you probably never bothered to read about it's proper usage, like most of the people who whine that a zapper doesn't work did.
And again I have to say this for the, what, 10th time. Dang stupidity strikes again!
I've used a variety of them across the years. I learned how to use them from Dr. Clark's instructions---her son after all invented them, and I haven't had one that didn't work (Of course I always do as much research as I can before I buy, and cheap ones never looked/felt right). That penny one was marginal, but it did work, just not well.
