>In general, VFP does a lot of caching to achieve better performance (content of the file is cached, content of the current record might be cached, old values are cached). It is not a secret that cache can get out of date and data can get out of sync. If the app needs up to date information, it should make sure it has it by locking and/or refreshing data.
