Downloads are possibly not in a different thread

I haven't investigated this thoroughly yet, but can dig deeper if nobody knows what the problem might be.

I am at the stage of a first pass integration of the latest JSword with AB and a lot is working but when I try to Download Documents I never get to show the status of the download. The system pauses until the download completes and then allows display of the status screen - but by this time the download has completed. So I wondered if the download thread had accidentally been removed.

Here is the logging when I download Gill and I have noted the place the pause occurs for the download:
