I was relying on Sandboxie as the surfing protection of choice, but it will never support 64 bit.  I'm wondering what people running Vista64 are using that's similar?

I liked Sandboxie because it was easy to turn it off when I wasn't using it.  Kind of a pain to reboot before installing even the smallest utility.  I don't like firewalls and av shields.  I'd rather use something that just traps and redirects disk writes like Sandboxie.. or at least a similar idea.
