Hello,
http://wiki.squeak.org/squeak/2332 'Mouse button tester'
has
m := Morph new. m on: #mouseDown send: #value: to:[:evt| evt redButtonPressed ifTrue:[m color: Color red]. evt yellowButtonPressed ifTrue:[m color: Color yellow]. evt blueButtonPressed ifTrue:[m color: Color blue] ]. m openInWorld.
red and yellow button work, but the blue button brings up the halo as it is noted on the wiki page (tested with a three button mouse).
I wonder if there is a way to make the change of the button to blue possible?
