Troy, first off, welcome to the forum.
Pull up a chair and join in the fun.... second, you should contact CS about this. They are very nice, and they would want the chance to help you with this problem. They may have you try a few things first (and may be stuff you've already tried), but if that doesn't fix it, I'm sure they'll want the opportunity to replace it for you. And if you send the misbehaving atty back it will afford them the opportunity to look at it, and that just might help the rest of us.
There was another forum member here (can't remember who or which thread ATM) that was having problems with the "C" leaking, and I don't think we ever got them sorted either, so I suspect maybe there's a small number with a mfg glitch of some sort (you've obviously isolated to the atty, and from what you've said I don't think this is down to anything you're doing or not doing). I've been vaping with the "C" since the end of November w/o one leak, and most who have been using it are having the same experience, so hang in there. Whatever the cause of the problem you're having, it would seem it's not a common thing.
