Hi Bruce,
This is my first week in a LONG time too, so good luck!
If you open a Finder (Tools->Finder), and search for "about" (selectors), you will find a bunch of things that respond to "aboutText", like "SystemWindow," and "ComposableModel."
The little drop-down arrow in the upper right of these system windows has an "about" item in the menu, and I just tried adding and aboutText method to the Spec Example "ApplicationWithToolbar" and the about box displayed the text I returned from that method.
I hope that helps, and maybe we'll both be able to figure some things out!
Take care,
This is my first week with Pharo. I have been moderately successful in learning how things go, but I cannot seem to create a HELP|ABOUT dialog. Pointing me in the right direction would be appreciated.
