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
