Hi Marcel,

Thanks! That helped.  I was able to update to #421 after running this. 
Should this message be sent as a postamble script or preload script or 
somesuch?

Now unfortunately the (64-bit image on OS X) locks up (no crash) at 
update-nice.422.mcm, "Installing Kernel-nice.1127".  :)  In 
SqueakDebug.log, there is the following:

MessageNotUnderstood: TextMorph>>currentHand

For the record: it has been very useful to upgrade the 
MonticelloConfigurations package to the latest version, so I have the 
ability to send e.g.

MCMcmUpdater default doUpdateUpTo: 421

Thanks again,
Tim
