I've been using Parallels since version 4 and it runs @ 100% on my Mac Mini with Moi. Version 4 can also be found a bit cheaper than the current version 6 if you like bargains! I allocate Parallels 2GB of RAM out of the 4GB installed in the machine and it can easily handle the fairly complicated drawings that I have done.

Moi is the only Windoze program I run, and I will do anything to keep it that way. LOL

Cheers,

Chris
