Workbooks auto-running on open

When opening an existing Toad Workbook, any workflows that have been created using the Query tab (SQL code) and not the Diagram tab, automatically run. Is there a way to turn this auto-run off?

Version of TDP you're using?
Also, if you save the workbook without data, then none of workflows should be auto-executed on open.

Version 6.2

I have save data option set to 'Never'.
