[Quoted] I was just saying that making the CBO do what your want is very difficult. Sometimes the CBO seems to have a mind of it's own but not a very smart one. Also sometimes thing just become too compilate because you have to take too much factors into consideration to be cost effective. The quest for inteligent life in the CBO is one of those things I like to avoid because I think it would not be cost effective as it would take a lot of time.
