No, none at all. The main AppKit thread is the thread that will be
repainting your progress bar. If it's blocked, it can't paint the new
state of your progress bar.

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
Your question was if there was a reliable way of doing it, and as you
have experienced, that's the best you can hope to achieve without
using a separate thread.

Sean,
AppKit is using -[NSApplication updateWindows] for some of animation
thread synchronization tasks.
If you experience animation not properly starting up with blocking
operations, you can kick start the animation by calling the method
before going into the operation.
