If you really want to up security from 1.0 (not adverse to that), then why not go to 2.1 as used by Win7? Win7 is still in support from MS -- and they haven't indicated a need to upgrade to 3.x for security reasons. 3.x may have new security features, no argument, but that doesn't mean 2.1, is insecure. > I do *not* believe that "default to version 1" is acceptable. > --- But does it have to jump to 3? I.e. Why not go a more middle route of 2.1 -- as it is still security-supported by MS. Ideally MS would find some bug in 2.1 and allow 3.x to be an upgrade to Win7, but until then... Linda
