I attempted to re-install Vanguard (from a new download) to see if it improved the CPU consumption. It didn’t. But in the process I was reminded of an issue I ran into when I moved to Windows 7. Some programs, especially those not originally intended for Windows 7, may need to be installed by running them as Administrator. The first time I re-installed Vanguard I received a prompt at the end from Windows 7 stating that the program may not have installed properly. The next time I re-installed I ran the install as Administrator and did not get the same warning.
