flyspell and lazy font locking

[Stephen Eglen]

Has anyone been able to hookup flyspell with lazy fontification?

I'm trying to emulate the behaviour in Word where it checks other
words also on screen, but not near point.  M-x flyspell-mode checks
words as they are edited, so other words that are on display do not
get checked until the point moves over them.

(setq jit-lock-stealth-time nil)
(jit-lock-register 'flyspell-region nil)


which kind of works, but when I first run the command, point is
temporarily moved to the top of the buffer and the spell check
started.

Anyone got this working?  (On Emacs 21.3.50)

Thanks, Stephen
