In our old system, 6.0, when you submit to QA, the submit window closes immediately, and after a while, you see your files on QA. For submitting to production workflows, somehow it was customized such that the "Submitting Files..." pop-up window doesn't even close until all submission tasks are complete, including the pre- and post- scripts, assumedly.I upgraded to 6.7.1, and in the submissions to Prod (using the exact same wft files), the "Submitting Files..." window closes right away.Can anyone provide a clue as to how this might have been implemented - where to start looking - so I can compare last version versus this one?Thanks in advance.Sue H
