Hi, I used the English version Zen Cart v1.3.0.1 (English is default language) and installed two language packs (traditional chinese(tc) and simplified chinese(sc)). When a customer uses tc or sc, everything is fine until he logout. The logoff screen shows in English but not tc or sc. What I want is to keep the favourite language that the customer chose even he has logoff his account.

Could anyone help me to solve this problem? Thank you.
