I am writing a small zimlet and trying to get its menu to display in different languages. I have created a com_test_zimlet.properties, com_test_zimlet_en_GB.properties and com_test_zimlet_fr.properties. My default language in preferences is English->United Kingdom but when I fire up in dev=1 mode the labels are missing. If I switch to French or English->United States then the correct labels are shown. What am I missing please ? Thanks.
