i'm trying to run two instances of windows XP at once i can get them open and working just fine but then once I start opening programs (a pretty low intensity internet app), one of them grinds to a halt I've got a dual 2.66 mac pro with 4 GB of ram -- and I can see in the activity monitor that in total my processer usage isn't exceeding 60% and I've got at least an extra 1 GB of inactive ram... so I don't feel my computer is maxed out really anyone been able to do this successfully?
