Hi Bruce, your subject is very confusing: it sounds as if ScriptManager does not work in Pharo 3.0 which is not the case!!! For instance in a fresh and clean Pharo3.0 image (latest #30678 build from today) it works without a problem. Just go to "Tools" -> "Configuration Browser" and load the package "ScriptManager". I dont know why you forked an own custom project for ScriptManager (http://smalltalkhub.com/#!/~bprior/ScriptManager) instead of contributing... If possible make it a private project or rename it - otherwise this is really confusing to others. And you are duplicating efforts - since in the offical ScriptManager this icon issue was already fixed long time ago after moving to Pharo 3.0. Regarding your problem: replace "UITheme current" with "Smalltalk ui icons" on all places and you are done. Thx Torsten
