Hi John, the "3" at the end of 3.3.54.3 is a developer's notation. It allows them to know what has been implemented it to the current release...If you downloaded from
http://www.paritech.com.au/paritech/support_PULSE.html and "Help about" shows 3.3.54.0 then you are running the latest version....The version number 3.3.54.0 refers to the over all build of the Pulse client.
