The scrolling bug is caused by this change:


Morph>>handlesMouseMove: anEvent
"Do I want to receive mouseMove: when the hand passes over the receiver?
Rules say that by default a morph gets #mouseMove iff
* the hand is not dragging anything,
+ and some button is down,
+ and the receiver is the current mouse focus."
---> self eventHandler ifNotNil: [^ self eventHandler handlesMouseMove:
anEvent]. <-------
anEvent hand hasSubmorphs ifTrue: [ ^ false ].
(anEvent anyButtonPressed and: [ anEvent hand mouseFocus == self ])
ifFalse: [ ^ false ].
^ true

There seem to be some unintended behavior because of this change.
