That's interesting/curious.

You're right that if I get there via the Plugins button it works as expected.
You're right that getting there via The MIDI/Audio drivers option gives the hidden-dialog lockup.

What seems odd is that in the former case the "Options" dialog open in the foreground, but in the latter case it opens behind, resulting in the lockup.

Clearly via Plugins is the neater option, but there's still clearly a bug.
