Look into re-adding the Stop button and investigate why it never worked correctly. See if there is a short term fix for this.

  • Re-add the stop button.
  • Investigate how it worked (or didn't work).
  • Generate tasks required to make it work.

    Had a quick look and some initial thoughts - looks like Taverna delegates stopping of workflows to the FreeFluo enactor engine so maybe it is is here that the problem lies. The code calls engine.cancelExecution(engineId).   you can find the status of the "cancellation" and with some workflows it seems to get stuck on "CANCELLING" no matter how many times you ask it to stop.
