hey... in reference to the question of whether scripts get completely loaded into memory or not... I believe that Ruud talked about that in his interview... To my understanding and experience, kix loads the script and ALL related scripts into memory.
I once had my primary script fail... and after a long ammount of time, I found that a script 5 levels down from the first (1 calls 2, 2 calls 3, etc..) was missing a quote or paren... fixed it, and the first script ran mint. Baffled me and my post here (about 1 1/2 years ago) was unanswered...
