I am running a restaurant database for an annual restaurant guide with two tables. One table has the facts & figures (ie tel no, address, prices etc), the other has the 2004 reviews, which have been imported from word/exel. The tables are linked in a one-to-one relationship by ID numbers. Whenever I try to run a query using info from both tables, I get a message 'unable to open query in datasheet view, possibly because another user has a source table open in exclusive mode'. I have shut everyone out of the database except me and re-started my machine but I get this message every time. I have checked that the database is in 'shared' mode. Can't find a way round it.
