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.

Hi all,
I'm trying to make a cheap, modal, indeterminate progress dialog, but
I'm having trouble animating the progress bar.

know I
should not block the main thread. One day...)
The docs for NSProgressIndicator's setUsesThreadedAnimation say "This
value is only a hint and may be ignored". Indeed, sometimes it
animates
and sometimes it does not. I can't find any pattern.
Is there a way to reliably make an NSProgressIndicator animate while
the
main thread is blocked?
Thanks,
