Another thing I saw at PluggableButtonMorph: if you bring up the context menu and click on "show actions", a walkback comes up that PluggableButtonMorph does not understand #target.

1.3- 13380 latest update. Now I think that this is because my vm has a bug with the refresh of the screen. if I resize it the system looks ok.

Re: [Pharo-project] suspicion update: method in MorphExtension

by StÃ©phane Ducasse

Exactly this is what I see now update: aParameter |state| aParameter ifNil: [^self]. getLabelSelector ifNotNil: [ aParameter == getLabelSelector ifTrue: [ (self labelMorph respondsTo: #font) ifTrue: [self label: (model perform: getLabelSelector) font: self labelMorph font] ifFalse: [self label: (model perform: getLabelSelector)]]]. state := self getModelState. (state ~= (self valueOfProperty: #lastState) or: [ getStateSelector isNil and: [aParameter == #onOffColor]]) ifTrue: [self color: self colorToUse. self setProperty: #lastState toValue: state]. aParameter == getEnabledSelector ifTrue: [^self enabled: (model perform: getEnabledSelector)]. getColorSelector ifNotNil: [ | cc | color = (cc := model perform: getColorSelector) ifFalse: [ color := cc. self onColor: color offColor: color. self changed ]]. The debugger was showing to me MorphExtension and in fact the method was in PluggableButtonMorph. Now I cannot reproduce it of course....

Hi guys I need help. I do not know why the image is so slow at startup and also why I cannot really bring an interrupt. Tomorrow I'm traveling. So no time to look at that. Stef
