I have an Access 2000 DB which appears to work fine, but if left for a while without doing anything the message 'You cannot carry out this action at this time' appears when you click on anything or try to change data. You cannot even close the form. The only way out seems to be quitting via Task Manager. The form only has one record at any time, but the DB is a multiuser with a remote backend. Anyone else seen this or know of a fix?
