Here's Jesse Welton's change set to fix some problems with TextMorph losing 
focus.  I nominated this awhile ago, but didn't include the change set.  It 
fixes a really annoying problem that results in characters going in 
backwards because of a loss of focus.

Note the changes precede the latest changes to TextMorph from SqC, so it's 
possible they are no longer necessary (or don't work).

Fixes TextMorph to retain the current selection and other editor 
information when its extent is changed.  This should prevent the selection 
from being reset by merely typing into TextMorphs in dynamic layouts."!
