Hi,
the german language seems no to appear in the Options-General-Language, even if the deutsch.xml is in the language folder. The file has the date of 24.10.2013.
An old bug is: No support for german language keyboards. I don't know, if this problem occures also on other keyboards, but it is really a pain to input names for cues, pallettes etc. if all special characters are mixed up on the Keyboard.
Regards
Axel
