So twice now, I've "finished" the mission. I blow up all the Jem'Hadar ships, and nothing happens. The Enterprise is floating around, dead in space, and is not repairing, which I hear it's supposed to do. There are no Jem'Hadar ships on the map (I assume - I full impulsed around quote a bit of the map, pressing tab, and there's nothing there that I could see). The mission does not complete.
Edit: Only on the third time, after changing the difficulty down to normal, do I get the dialog pop ups, and a cutscene. These definitely did not appear at all the first two times.
