Hi, Because this code does not work with rubric: | text editor |text := ['Figure DrGeo ' asText, TextConstants CR, DrGeoCanvas viewLess axesOn gridOn view asText, TextConstants CR, 'Ici...' asText].editor := RubPluggableTextMorph on: text text: #value accept: nil readSelection: nil  menu: nil. Although this one is ok: [..] editor := Smalltalk ui theme builder newTextEditorFor: text getText: #value setText: nil. Thanks Hilaire -- Dr. Geo http://drgeo.eu
