From the developer:
While many viewers share the Roaming\SecondLife\[avatar_name] folder for chat, Zen creates a separate folder for all the chat logs and user settings. You do have the option in Preferences->Privacy to change the location. If you don’t, then the viewer will only see chat that has happened in it. Support is via the developer, Zena Juran, in-world by direct contact, IM, or note card.
