hello andreas,
positive. i double-click on the "Squeak4.0.2.exe"
that comes from http://ftp.squeak.org/trunk/4.1rc3.

Smalltalk vmVersion says

  'Squeak3.10.2 of 11 February 2010 [latest update: #9314]'

That may or may not be a clue ;)

I tried to debug into it:
SMSqueakMap instVar objects seems to be nil where it should not.
so i "browse full", then do "inst var defs" for objects, which
gives
SMSqueakMap>>purge which sets it to nil, and
SMSqueakMap>>copyFrom:aMap which copies from the aMap objects.

Implementors of objects gives
SMSqueakMap>>objects ^objects

hmm? i have no clue where this thing is supposed to be initialized?
cheers,
wolfgang
