Color-coded pop-up messages can appear on the lower right of Workbench to indicate success or failure of a job.
Successful jobs have a green pop-up message indicating the success.
Failed jobs display a Job Failed dialog box by default, asking if you would like to view the log.
Workbench has a preference that allows you to change this behavior to display a red failure pop-up message instead of the dialog box.
To change how Workbench displays notifications for job failures:
Select Tools > Preferences.
Select Behavior in the left pane.
In the Interaction area, clear the Display an error popup when foreground jobs fail box. The label changes from True to False.
This disables the Failed Job dialog box.
Now a red pop-up message displays at the lower right when a job fails.
NOTE: You can click the success or failure pop-up message to open the log, which is the same as selecting the Output status bar pane.
You can always change back to display the Job Failed dialog box by toggling back to True for the Display an error popup when foreground job fail option in the Behavior section of the Preferences dialog box.
