In the example above, I've also done "possible numbers" for all the remaining squares, and I still can't eliminate 1 or 4.

That's my problem, FE. I do them online a lot, and when I tried to up the level, I could never figure out the 1's, 4's, or 7's. So, I'd get rollin' on the board and then get stuck and could not get any more clues from the board. I took that as a hint that I needed more practice on the easier ones. I've never read official directions on how to complete the boards, so perhaps I'm missing one of their tecniques to finish them or something?
