How is it that you are on the surface, and still getting an increase in CO2 levels? Are you capsised or something? Shouldn't air be replenished from the upper hatch? If you can go yourself to the bridge to some lovely sigh-seeing, air should be automaticly ventilated.

Am I right? At least that is what my experience dictates. Everytime I emerge, air is instantaneously ventilated. No need to pump it, or to activate any kind of ventilation - as it is the case with a sim like "dangerous waters", and still, as I recall, that only being needed for pressurised air.

Anthony,
Yeah, If you have damage and are having problems keeping the boat from sinking, you could have rising C02 levels because even if your surfaced but are running at a depth of 25' or 30' (I'm really not sure of the exact depth that the game is set), the boat may think your submerged.
The Alt-Tabbing thing is probably the problem here like Armistead says, however, keep that boat as surfaced as possible in your conditions with the storm ect.
Sounds like your having an exciting game. Also, keep your repair team going and make sure to swap them out when they get exhausted, they may fix a lot of the damage. You probably already know all of this, I'm just popping off suggestions if I were in your place. Hope you get back to base and watch out for the planes!
