No, I'm sorry, but if you'd taken the ten seconds to consult Inside Mac
before you posted this, you'd have seen that IsDialogEvent does no such
thing.  It is DialogSelect that will do the cursor blinking on a null
event.  IsDialogEvent by itself will do exactly nothing.

"A book is the product of a contract with the Devil that inverts the Faustian
 contract, he'd told Allie.  Dr Faustus sacrificed eternity in return for two
 dozen years of power; the writer agrees to the ruination of his life, and
 gains (but only if he's lucky) maybe not eternity, but posterity, at least.
 Either way (this was Jumpy's point) it's the Devil who wins."
