out of action person bets, angleshoot????

[GreedIsGood]

I'm working on the assumption that the Hero's hand isn't hidden and the fact that the out-of-turn player had just done this a couple of hands earlier, and presumably had been told then.

Now the OOT player could easily be clueless and can't figure out that you can't click your action in advance in a live game, but that's not how I read the OP. To me is sounded like the OOT player knew exactly what they were doing and were trying to change hero's action with their non-binding raise.
