Hi Dmitry, Matthias, Thanks for your replies.
The Racket installation is a fresh one, using the Mac DMG download from the website. It's my first go at Racket :-) I tried deleting all ZO files in the Racket tree, but that broke my Racket installation. Re-installing Racket fixed the issue for now; I just hope it doesn't come back.
