Changing for example the document from draft to the final version via the option field of class option in the tools->document preferences window results into an error and raises the class switch error box:
> Class Switch-Fehler: > Fehler: Undefinierter Zeichenstil > Beschreibung: Der Zeichenstil Code ist aufgrund einer Klassenkonvertierung von > scrartcl nach scrartcl undefiniert The error occurs with character styles set with linguistics.module and logicalmkup.module in all KOMA-script classes. The error occurs with many document wide commands like changing fonts etc. I have tested it with a minmal file to prevent other possible error causes. Peter
