no luck, huh.
anyway, i found the OSC world-zones folder hanging around my desktop from back before i switched to zen. so i opened the SQL file and read it and it looked benign enough to try.
first i backed up the database in admin-->tools, then went to tools-->install SQL patches and cut-and-pasted the world_zones.sql file.
seems to have done the trick. i don't know how perfectly up-to-date the values are, but it looks good so far.
also, i'd removed about 2/3rds of the countries in the zen default list. this has added a full list of zones to the 50 or so countries remaining, without (as far as i can tell) interfering with anything else.
i'd attach the file here but it's too big for the attachment limit. luckily it's not hard to find on the OSCommerce contributions page (i used v1.9)...
