Hi all,
loading this package triggers an Exception - see below.
Since I triggered the package load thru UI, a HandMorph method is still
active on the stack.
But since I removed an ivar, that's the old method, not the up-to-date
method...
Hence it has wrong ivar offsets, and access the wrong instance variable.
Is there any way I can abort/restart the UI process in postscript?
Or should I use complex preamble that duplicates HandMorph class, let it
adopt current hand,
then complex postscript that migrate hand to the updated HandMorph class?

If you have a less overkill idea, i take it :)
