when you close the query, there should be an option to save because you have made changes... click no...
otherwise, include more information...
what vertion access are you using...
how are you hiding the field??
what i typicly do in access when working with a query, is make any criteria or sorting fields hidden right from the start, and i include a star (*) that is the only thing visable... i do this because none of my users even see any queries, they see every thing through forms...
hope this helps.
