I am wondering: when executing "PreferenceNG initialize" in an image with vector graphics it seems to break the image. I guess a race condition. To avoid this situation, I suggest you edit this method as follow: PreferenceNG>>initialize ThePreferences ifNil: [ThePreferences _ Dictionary new]. ... It will allow to add the new preferences from the data array and reset the existing ones with the default values from the array (this what happen when requesting a new preference already in the system, it just updates the existing one). A few limitation: <ul> <li>It will not migrate type of existing preference (should be done by hand by inspecting the object or removing the whole preference and initialize again), I prevent it by purpose so a user does not mess up with the type. </li> <li>it will not remove deprecated preferences (the ones not anymore in the data array). Should be removed by hand. </li> </ul> Hilaire <div class="moz-cite-prefix">Le 13/05/2022 à 22:42, Juan Vuletich via Cuis-dev a écrit : </div> <blockquote type="cite" cite="mid:627EC2AC.4000100@zoho.com">Hilaire, please check that the use of Preference NG is reasonable. </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>
