We run ACT 2007 on our terminal server and have a large number of contacts. We have about 7 end users consistently complaining about ACT performance being very slow. We have introduced two new computers running VISTA and just learned that VISTA and ACT 07 are not comparable. Our options according to our IT and ACT consultants are to either upgrade to ACT 08 (10 new licenses). Please advice if upgrading to 08 or migrate to ACT on the Web would be a better option for us since we have the performance issues that will continue until we upgrade our terminal server.
