When I run a query from a form I can get a Query returned no hits Information Dialog. When I run the same query from the Query Builder, there is no Information Dialog.
Create a Form backed by a structure table.
Add the Cd_id field.
Enter Query Mode. Enter "= ThisDoesNotExist" in the cd_id field.
Hit Run Query. The Information Dialog shows.
Open the Query Builder window and run the same query. The Information Dialog does not show.
