Well, 8 out of ten.
Good fun! Good challenge!
I knew the answer to one of my wrongies, I guess I just clicked the wrong piddly-dit.
And the "correct" answer (which I got) to one of them is technically incorrect, but I won't say why or which* lest it spoil it for others.

* Added later.... Swampfox nailed this error on number three. Good show, old man! I took it before reading all the posts so I'd be taintless.
Wait a minute.... that didn't sound right.
