Different Results When Running Vs Step Through

My workbook contains several worksheets with queries to external SQL Server database. All queries use background updates. Each query uses a parameter for the SQL query string. The parameter value is obtained from E2 Reports!B4. Manually changing this cell returns results on worksheet Job Summary in range("A6:K6"). This works great!Worksheet Order Details contains a list of job numbers in column B.

I wrote a VBA sub that loops through these jobs, changing E2 Reports!B4 for each job. I then call the Application.RefreshAll function. Finally, I copy "Job Summary!A6:K6" to a row on worksheet Order Summary. If the next job is the same order, I copy with a paste special to add the results.The problem occurs when running the VBA sub. If I step through the code, waiting for the RefreshAll function to finish, the correct values are returned. If I step through fast, without waiting for the RefreshAll, the values for some jobs are copies of the previous job, but other jobs are correct. If I hold the F8 key down or hit the F5 key, all values are the same as the first job.I've tried DoEvents, turning off screen updates, and turning off background updates.
