Hello! > (Form new extent: 300 @ 400) edit" > It didn't work for me in Squeak 3.8 (on my Macintosh). In system browser you can open class Form and in editing category along with #edit there is #morphEdit method. It is work in Morphic. At least on my computer this work: (Form extent: 200 at 200 depth: 8) morphEdit Good luck. Alexej.
