Strange Autoplay behavior

Whenever I insert a USB stick into my PC, I get presented with this:

When clicking on the "Using Directory Opus" option, bugger all happens. The autoplay window closes, and that's it.
It this a known phenomena? I invariably select the top option, but the less I have to use explorer.exe - the better.

Cheers,

Simon

Juar answering my own question: That feature only works if DO is set as Explorer replacement.

That sounds like a bug which was fixed a few months ago by Opus 9.5.6.0.
