Sending the message #doOneCycle is forcing one loop of update of the UI, i.e. the requested Morphic operations are forced to take place immediately (mostly?) Your forked process, with the delay, just delays your Morphic operations once the start up script has been entirely executed -- or something like that. I should add a note in the ad-hoc book section, but I don't understand fully the evolution of the issue -- was working with previous image and not anymore now if the #doOneCycle message is not send. I opened an issue <a class="moz-txt-link-freetext" href="https://github.com/Cuis-Smalltalk/TheCuisBook/issues/15">https://github.com/Cuis-Smalltalk/TheCuisBook/issues/15</a> to not forget about it. Feel free to add comment to this issue when needed so we can fix the documentation appropriately.

Thank you. It is better then my fork+delay. Could you explain me a bit why the "doOneCycle" work ?</div> </blockquote> </blockquote> <pre class="moz-signature" cols="72">-- GNU Dr. Geo <a class="moz-txt-link-freetext" href="http://drgeo.eu">http://drgeo.eu</a> <a class="moz-txt-link-freetext" href="http://blog.drgeo.eu">http://blog.drgeo.eu</a></pre> </body> </html>
