Thanks, John. I downloaded the 2.8 image and changes files, and the V2
sources, and launched squeak with those. It opens fine, if old looking,
and Alice is in there. I did a Wonderland new. and ran into an error:
mustBeBoolean
"Catches attempts to test truth of non-Booleans. This message is sent
from the
interpreter."
self error: 'NonBoolean receiver--proceed for truth.'.
^true
The offending code is
areasRemainingToFill: aRectangle
^myCamera drawSceneBackground
ifTrue:[aRectangle areasOutside: self bounds]
ifFalse:[Array with: aRectangle]
where "bounds" in the ifTrue branch is highlighted.
A little more digging reveals that senders of bounds have something to
do with AlignmentMorph, which is old stuff -- is the problem that ny VM
is too "new.?"
Any suggestions as to how to proceed? Is there a way to cast "bounds" to
the Boolean requirement? Sorry, that's my C showing.
