Hey, no apology necessary.  I have no way of knowing what's going on
behind the scenes, but I also didn't like the notion of just walking
away from a busted thing, so given the silence, figured it's better to
post the working something I've got (wart and all) than to let the bug
go unchallenged.  (take that damn bug.. pokes it with sharp stick;)
