Use the Cleanup button to remove records for foreign language labels and prompts for which the corresponding English record is null. (This situation sometimes arises when a label or prompt that was available in an earlier version of Opera is no longer used in the current version, leaving the foreign language counterpart for that label or prompt in the database with a null English equivalent.) Failing to remove these records can create display problems on some forms. When you select the Cleanup button you will be prompted to confirm the action. A backup of the affected tables will be created automatically prior to the cleanup.
