Thanks for the suggestions Tom. I know about that things, but the original code

trimmed out for the example.

Unfortunately that doesn't help.
I think the issue should be related to dispatches, because it won't happen if I

Performing asynchronously and blocking the main *queue* are not related things.
The main queue is a serial queue, it only executes one block at a time. At the
moment, it's executing your block, stuck in your runModal call. That runModal
call will not come off the stack, and the block finish
Ahh, okay, thanks for the explanation Tom, now I got it.

If you want to block interaction with a document, you can use
It's a live video app, where rendering happening on a CVDisplayLink thread, so
the app still running and do its job while an OpenPanel (or SavePanel)
