Hello all,
To save morph and restore it is a basic behavior which is broken since Squeak 4.5. This is a bug. Beginning from 4.5 new Squeak user will get a debugger window open in a few clicks. This bug happened as a side effect of pushing Environments package into the Squeak image beginning from Squeak 4.5. No one uses Environments; there are significant use for morph saving. Squeak needs this ability. Maybe it is easier to remove Environments from stock Image and to fix the bug introduced by that package.
Introduction of new packages need not to break useful things...
