Thanks for the replys. I forgot to mention I am using XP pro SP2. Parallels is the only thing that chews on the processor so heavily. It might be the Airport Disk utility that runs in the background. When I was away from my home network (Airport extreme 802.11n), I was trying to show a coworker and it ran fine 10% or so. Back home, back to 30-50%. Only thing different was wireless with the Airport NAS. I will look into this further. But as it turns out I am starting to use the Fusion beta more and more. Unity is a lot better IMO than Coherence and the product lets me use my existing network w/o making changes to fw0 ports for VPN access, Airport disks etc. Just a little too fundamentally buggy for a version 3 release.
