Thanks in advance for your time
Is it possible that BBEdit is still running? Acrobat waits until your editor is completely gone from memory, so if it's still running (even with a different document open), Acrobat will continue to wait. I am using TextMate, and I usually have a lot of other files open in editor windows. I have to shut down the editor completely, and then Acrobat will import the saved script and come back to life.
I just verified that this is still working as it used to with Acrobat DC.
