FCKLang problem

Hi all,

I try to create my first plugin. Everything work weel, but I can't retreive localized text. I do not receive any error!
When my dialog box is displayed, the text defined in language files (en.js, fr.js) is never retreived.
I thing that FCKLang["MyText"] do not find the language files, nor oEditor.FCKLanguageManager.TranslatePage(document).

FYI, I have the same problem with the findreplace sample. Do I miss a param somewhere?

Thanks,

Gilles
