Do I have to try and keep it there until the time runs out, or hit some kind of confirm, or what? Because I've tried staying in the highlighted area before, but was still told I failed and needed to try again. I wouldn't put it past the game for this to be some kind of bug or glitch as well, but I guess that's why I'm trying to get as much info as I can.
Edit: Ah, made it work this time. Think it was just being finicky or laggy about where it registered the bar as. Though, once activated, I now haven't been able to actually do anything with it.
