Hello, I guess again that the following example only breaks on my computer (this time it's probably true by definition). Any ideas about circumventing the problem are most welcome (PS: "Translate your text to English" is not considered a valid answer :). \mainlanguage[sl] \starttext \startitemize[a] \item something \item something \item something \item something \stopitemize \stoptext !

Thanks, Mojca (who is going to try the latest version now, but I doubt that it makes any difference)
