When you open the Job Setup window in Automation Engine Pilot, sometimes no thumbnail is shown while in other cases it does show a thumbnail. Is there a way to automatically specify which file's thumbnail it should display?
There is no user-controllable preference setting to specify which file's thumbnail is automatically set as the job thumbnail.
The icon for the job is set automatically,
when it is not yet set
when one of these tasks finishes with success:
Export ArtPro to PDF task
Normalize PDF task
Normalize PostScript / PDF / Illustrator 8.0 File task
To set your_file's thumbnail in the Job Setup, make sure that your_file is the first file in that job which runs through any of the above tasks.
You can also manually set a file:
Open the Job Setup window.
Right-click on the thumbnail field.
As long as you did not run one of the above tasks, the thumbnail place holder will show "No file selected".
