(LCD monitor mystery)
I was wondering why I can dust the screen on my LCD monitor everyday but the
next day right in the center is a large (approx 14") circle of dust again. What
is the explanation for that and any way to prevent it from happening on a daily
basis?

A friend of mine was telling me that when you buy quantity packs of
transistors that they're usually slightly flawed or out or spec rejects. Is this
true?

(subject - lightning protection)
I get a lot of thunderstorms where I live this time of year. I use a surge
power strip but I don't know if that's enough. I would like something better so
I'm not as worried about my computer system.
