The particular fix Matthew pointed me to is popping up the menu on a
mouse down event, not a mouse up event.

http://git.racket-lang.org/plt/blobdiff/27aa99944657c5827eee3772f715df7dd971d1e0..0377bda9474f8848a97509ace898174c83361006:/collects/framework/private/keymap.rkt

So I guess there's something else going on, too (because that's the
code that pops up the menu with the check syntax items).
