MicroSqueak [1] has a hierarchy of classes for making a tiny image. 
MForm in that hierarchy has a method:

MForm>>beDisplayDepth:

         specialObjectsArray at: 15 put: self


This is pretty neat. It says take the Form you made and make it the Form 
that is the Display.
I run the 59K image with the Etoys 4.1 app to get an older virtual 
machine and a separate Mac OSX window appears.
And then it disappears. Pop.

I want it to stay. Don't go anywhere. I'm guessing a process like 'the 
UI Process' in the ProcessBrowser is required to create a loop to keep 
the window static on my desktop. Then again, maybe that process is just 
there to constantly poll for events to send to SmalltalkEditor.

BitBlt class alphaBlendDemo is equally ephemeral. What's the difference 
between a Form that disappears on "restore display (r)" and a standing 
window?

Thanks,

Chris
