The full walkback is on http://minnow.cc.gatech.edu/squeak/3146

One thing I don't understand is when I evaluate "submorphs includes:
scrollBar" from the walkback I get a "true". But obviously
showScrollBar did not return though. 

showScrollBar
	(submorphs includes: scrollBar)
		ifTrue: [^ self].
	self resizeScrollBar.
	self privateAddMorph: scrollBar atIndex: 1.
	"scrollBar changed."
	retractableScrollBar
		ifFalse: [self resetExtent]
