Workbook doesn't pick up latest version of query automatically

Hi all

has anyone come across the problem in BI7 where an alteration to a query already existing in a workbook is not automatically picked up.

My workbook continues to use the old version of the query, unless I remove it and respecify it within the workbook.

Is there something I should be doing to tell the workbook to pick up the latest version?

Thanks

Hayley
