In Pharo 1.4 you just open the configuration browser: - either by evaluating "MetacelloConfigurationBrowser open" or via menu "Tools"->"Configuration Browser" - when it is open search for "ScriptManager" in the list of available Configurations, then select it and right click to choose "Install Configuration (Stable version)" from the context menu - now go to "Tools" -> "ScriptManager" Same procedure in Pharo 2.0 Bye T.
