<< I have been working with Mark Guzdial's tutorial on Morphic where he has 
the reader build an ellipse that falls more or less gravitationally. Every 
time in 3.1 when I add the instance variable "velocity" to the ellipse 
object, there's a brief pause (3-7 seconds) and then Squeak crashes 
completely.
 
 This on a Mac 9.0.4 system with the 41 latest updates filed in as of 
tonight. >>

Dan,

Where is Mark's tutorial located? (I couldn't find on either of the recent CD 
collections).

I had earlier loaded up all the latest updates, and thought I would try to 
recreate your bug on a Windows platform, but then couldn't find the tutorial. 
I _was_ able to create an Ellipse object with ivs: o1 and o2, and then update 
the definition with a velocity iv. But this is pretty naive without any 
context from Mark's stuff.

Jerry.
