diabolik the original sin "move game"

anyone else having probs with the move game, lock pick thing?
i cant figure out what i'm supposed to do. I tried the practice, soo many times,
i got past the first one no prob, but when it gets to the part with the wedge, i have no idea what it's trying to get me to do

It's very easy. Just run the cursor over each of the highlighted graphics until the lock is picked.
