Well, these zero windows are expected, no? You'll have to update the
window from your application, of course.

I don't know what's wrong, all I can say is it works for me. I have a
setup running where you can upload a file to (slow) flash and manual
window update throttles upload speed.

You might want to debug why the connection resets.
