In my mind, a well-formed nonogram is one that requires no backtracking. It's an interesting question though. I'll write some code in the next few days to check to see if my set of "unsolvable" puzzles include those with unique solutions given the clues.
Yeah, a "jump to unsolved" seems like its going to be essential. I'll work on that. I haven't heard of the scrolling issue. What device/browser are you using?
