Johnm, you seem to be clearing up my confusion today.
What you wrote makes perfect RW sense. This is such a cool game.
Well, after you figure out the new key controls GWX3 added, that don't (obviously) show up on my Quick Reference Card. I had my kitten walk across the keyboard last night and he sent my sub into a crash dive in shallow water slamming into the bottom and removed the controls from the bottom of the screen. He sat there fluffing his whiskers as I frantically dove into self-taught damage control. The boat survived and he went to sleep.
