Thanks Paul -- I actually found that not long after this thread was last alive (I leeched *all* of your site's Blitz stuff a couple of months ago because it rules!).
In fact I was thinking about this again today, weirdly enough, because I never quite got it right, and I remembered your engine had a function that looked like it would take care of this for me!
