ScheduledControllers - is an UndefinedObject !!!
could not reproduce problem.

Hi Theo,

I brought up a Squeak 7137
opened an mvc project.

Copied the code from the wiki to a workspace in the
Selected it and pressed Cmd-d to doit.

The result was an untitled window with the polyspiral
drawn inside.

So what did I do different from what you did?


Yours in curiosity and service, --Jerome Peace
