Thank you -- of course ! I had that "ui close" in my code !!! , I'd expected the form to take control until I exited the form itself and had not considered the code would 'fall straight through' to the 'ui close'
The example form now displays on Pharo's World and is active as expected. >From my experience with trying to get this example working, I think the chapter needs a bit of expansion & more explanation about some features used. The Class method creation verse the instance methods being an example. I guess the authors assume most people will have worked with Pharo without jumping straight to the GUI interfacing !! Thank you all for your help, getting this example running is a very important step to understanding Pharo's UI. -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html
