Rob,
Thanks for your reply. But what you say can't be so. As I said,
sometimes my 'hint' is accepted and the progress bar animates, and I am
definitely blocking the main thread with my own code at the same time.
But it only works sometimes, and I'm looking to make it work all the
time. But the docs are not encouraging.
