Hi Juan,

that solves it in the freshly compiled VM but doesn't for a prebuilt 
"202003021730" VM
------------------------------------------

Smalltalk imageName .  " 
'/home/p/download/cuisTest/Cuis-Smalltalk-Dev/Cuis6.0-5031.image' "
Smalltalk vmVersion .  " 'Open Smalltalk Cog[Spur] VM 
[CoInterpreterPrimitives VMMaker.oscog-eem.3148]' "
ChangeSet installNewUpdates.
Feature require: 'VectorGraphics'.    ==> it works

------------------------------------------


in the precompiled "202003021730" VM:
------------------------------------------

Smalltalk imageName . " 
'/home/p/download/cuisTest/Cuis-Smalltalk-Dev/Cuis6.0-5031.image' "
Smalltalk vmVersion .  " 'Open Smalltalk Cog[Spur] VM 
[CoInterpreterPrimitives VMMaker.oscog-nice.2715]' "
ChangeSet installNewUpdates.
Feature require: 'VectorGraphics'.   ==> still does not work


---- in the shell i see ------

VectorCanvas class(MorphicCanvas class)>>onForm:translation:
        Receiver: VectorCanvas
        Arguments and temporary variables:
                argOrTemp1:     DisplayScreen(2200x911x32

----------

i guess the reason of the different behavior is  because this VM does 
not have the VectorEnginePlugin, right ?

-----------------------------------------------


bye
Nicola
