Well, maybe because Comodo for Vista at this stage (Beta) is too buggy… nothing works as it should on some systems. Even on Windows XP I experienced few problems with suddenly losing internet connection… also with Home Networking… sometimes it works, sometimes you can’t access your network computers even though you were able to do that 2 minutes prior your second attempt… Also, it seems like they included so many options inside that Comodo became everything but simple for some beginner user profile. Another bad thing - It became little too heavy on system resources too.
