I have a question for someone that has computer knowledge. Not the using them kind of knowledge but the how they work kind of knowledge. Why does Amazon make me sign in significantly more often (or log me out more frequently if you prefer to think of it that way) , and enact stricter security measures when I'm on a 64 bit OS than it does when I'm on a 32 bit OS? It can't just be for funsies right? I've been using both and I can't figure it out. I was hoping someone could explain it to me before I had to resort to Google. .
