I'm trying to figure out how to use the moodle 1.9 interface to create a new language pack, based on a non-English parent language.
The problem I'm having is, when you go to Language Editing > Language Pack Maintaining > Edit words or phrases > Choose a file to edit, you get the comparison view, but the 'current' string on the left displaying the English version of the string.
In order to scan through the listings to look for changes I'd like these strings to appear in the parent language instead.
I've tried setting the site default language, and the user's language in their profile, but it won't change from English.
Anyone got any suggestions? I'm happy to hack the code if it can be fixed that way. If there's a config option I'm missing, even better 
The screenshot below shows what I mean (with Castillian Spanish (es_es) selected, which has International Spanish (es) as its parent language. it's the words on the left ('Add a new entry', etc) that I'd like to appear in the parent language.
Thanks,
Simon
