This appears to have been fixed by an upgrade in some other package(?), as I haven't changed any locale settings, and the metacity version on my system is still 1:2.10.3-2, but the menus now contain the American spellings.
At any rate this should be marked as resolved. -- Chris Roddy <[EMAIL PROTECTED]> -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
