The menu is there, but trying to click *anywhere* on the menu bar, on
any of the menus, doesn't work and results in a dialog box with:
Error in script file "regexp-replace.rktd": initialization for
menu-item%: prefix not supported for the current platform: 'meta.

I don't know about Stephen, but I'm using Mac OS X.
