Hello All,

I am very happy with this update, but it breaks language settings.
My machines are installed in Dutch, so I had 
Bestand Bewerken Beeld
in the Menu Bar.
After the update  We have
File Edit View 
so the entire Preferences menu is in English as well.

Is there an easy way to get this back?

greetings, Johan
