All queries and distributions work as filters. This means that the sets of bugs they contain may change depending on which element is the parent of the query.
Deskzilla allows to move and copy queries to different locations in the navigation area filtering bugs contained in the query parent elements.
To move a query or a distribution select it in the navigation area by clicking on it and then drag it to the required location. As the element is dragged over the navigation area the possible new locations are highlighted with red. Once the required location is highlighted drop the element.
To copy a query or a distribution, right-click on it and select Copy. Then right-click the element, that should be the parent of your query copy and select Paste.
