Hi,
I have installed DO12 over DO11. Everything is fine (updating my custom menus and toolbars with the new commands).
But some of (or all ?) the new commands are not translated in french, and remains in english.
Did I do something wrong, or not everything has been translated for now ?
Thanks for your answer 
(and thanks for all of your work, Jon and Leo. DO12 is amazing !)
Which commands? Are they on customised toolbars?
Try to change langage to english then french in Prefs.
@Leo there are untranslated commands everywhere, here and there.
@AlbatorV thanks for your help... I tried but it changed nothing.
Example : in full menu, "Commands", "Extract", "Get Sizes", "Use Files", "Join Files" remain untranslated.
May be "FullMenu" is an old toolbar ??
FullMenu is not one of the standard toolbars, which may be why only some of it is being translated.
You are right Leo, now I remember... as it's a very complete menu, I spent some time to translate it and now everything is fine
