I am running Mac OS 10.4.6 and aMule 2.1.2 on an Intel Mac. My Mac System Preferences > International > Formats is set to United States. Here is what I noticed:
1) The aMule preferences is not remembering the language settings. When I set the language to English (US) and then restart aMule, the preferences shows language set to "System default". If I set the language to English (UK) and restart aMule, the aMule interface is displayed in Dutch, but the language preferences shows Portuguese selected.
2) When I set the language to English (US) and restart aMule, the file sizes and upload/download rates are shown with dots. But the moment I open the aMule preferences, all the dots change to commas again.
3) The amule.conf file is not being updated properly. If I set the language in the aMule preferences to English(US) and then quit aMule, the amule.conf file is updated with "Language=en_GB". If I set the language in the aMule preferences to Estonian and then quit aMule, the amule.conf file is updated with "Language=en_US".
