Running an AMD here and had no problems, WIN2K Pro. I used P5 for about 8 hours yesterday and had no crashes or other problems. I doubt its a cpu problem. More likely an os related issue and perhaps even other programs working in the background. Several so called bugs people have reported are not bugs at all just users not understanding how to use the program. If you look at all post closely you will see the people complaining most have XP but not all XP users are having problems. No doubt there are problems that need to be addressed. Ron
