Hi Bert.
Looking at your work at http://lively-web.org/users/bert/squeak.html, in the top middle display Am I looking at a process browser and a "stack" of suspended and active contexts?
[] in BlockContext>>newProcess [] in ProcessorScheduler class>>startUp ProcessorScheduler class>>idleProcess
ctx[5]=rcvr: the ProcessorScheduler class
thx,
tty
