Crap. People around here say 'no problem' when all they mean is 'you're welcome'. Sounds like they've just given you their right leg, but hey, don't feel obligated, or anything.
It is also used when one passes someone too closely, and one's concern might be that one offended another, so one might say, "Sorry." The reply could then be, "No problem," meaning he/she did not take offense.
But, not saying, "you're welcome" seems to me as though some people are not comfortable with standard formality, and for whatever reason would like a substitute, that being, "no problem." Used like that it sounds to me like a regional usage, sort of like, "Howdie," instead of, "Hi."
