I hate to bust your bubble. But I am using the free version of SAS on XP pro SP3 at home and at work testing it out. At work I have an ATI Radeon X300 with the latest ATI drivers (8/20/08). No activity in Task manager at all with Trend Micro Enterprise and Windows Firewall. At home I have a Sapphire using same driver. NOD32 and Commodo Firewall. I am constantly closing SAS as it gets to 100% CPU. Came here looking for answers as I like the program.
As an afterthought, At work I have DSL 100% online at home I use Dialup seldom online, is SAS trying to access the Internet?
I also have 2GB RAM at work and 1GB at home, but I don't see how that would affect CPU activity.
