Unfortunately, although it always triggers under the same condition, it doesn't trigger every time I'm in that condition. In fact, I don't know that I've every been able to trigger it more than twice in a day, even when manually attempting to create the circumstances that might do so. And some days I haven't been able to trigger it at all. -- Michael Welsh Duggan (mwd@cert.org)
