I've caused Monty to retreat away in his balloon with Twitch and am giving chase with Wallace's airborne van, however instead of climbing on top of the van, I went to the churn/serve buttons (just investigating my choices) and now it won't let me zoom back out to get on top of the van. It says "Right Click to Exit" but right-clicking doesn't do anything. Quitting and reloading the game doesn't do anything either.
Am I going to have to play through the whole game again just to do this final scene? :(
