Thanks Joe, also brought this up in the long talk today with Apple. He said these Unix files are not Microsoft, as I thought, but Mac files. He said there are 100 reasons why this could have happened, so has no clue in the end.

You think rebuilding launch services could make the black icon exe files revert to the Word .doc they once were?

BTW, you use recommend Onyx? I was on it years ago for maintenance things that many have deemed unnecessary now, so I bailed a few years ago..
