I see we still have the "invalid use of Null" bug which means that the create command button on the Design tab for forms fails. First encountered this back in Access 2006 and am surprised it has not been resolved yet. Once you get this bug, there seems to be no way of resolving it without reinstalling Access and potentially recreating databases from scratch. And it has just hit me again on a database with 30 tables, 20 queries and 16 forms. Can this bug be sorted out please?
