I only defrag about once a month if I remember & can spare the time :) Also like Decadence I never shut off ZoneAlarm, the only time I'm not connected is when my pc is switched off, I love broadband :) Installing Poser on a seperate partition from your OS is also a good idea. I'd give it at least 20Gb to play with should keep it fairly happy especially with the amount of freebies about.
