The 2007 ZA ISS (3 seat license) is causing my computers (XP, Pentium 4, 2 gig RAM) to start much slower, perhaps by another minute or two. What's worse is that my computers now take over 10 minutes to shut down (and sometimes doesn't shut down at all)!!!!! It used to take about 20-30 sec before with the 2006 version. I now regret buying this POS.
