Hi, 

Poking a little I found that the problem is on
TextMorph>>keyboardFocusChange: first line:

	paragraph focused: aBoolean

Which was added on 5849TextMorphSelectionFix-rr

I read on TextMorph>>paragraph's comment that paragraph instantiation is
lazy so I think that we should use here the getter instead of accesing
directly to the variable.  Attached is my proposed fix but please
someone review it first because I know nothing of TextMorphs.

Regards,
Hernán
