Great! Thanks. It works perfectly in Pharo 3 but not in Pharo 4. I thought that the drawOn: aCanvas was mandatory. I'm so lost in morphic. Trying to understand the logic of it slowly. Unfortunately there seems to be little documentation and a lot of what is there does not work in Pharo 3 or 4. Thanks again for taking the time! Best Nacho
